How to create Cascading (Dependent) Dropdowns in Power Apps

[@RezaDorrani]

A recent update was made in Power Apps where "Result" is now "Value". Concept showcased in video works the same. Simply replace "Result" with "Value"

Hi Reza, Thanks for this wonderful video. Can you share video on cascading between dropdown and people picker field? Where on click from 1st Drop Down(Department), the people picker field(Managers Name) will cascade its options. Source is SharePoint list. I tried but unable to build connection between Active Directory.

Thanks Reza, clearly explained as always. Just as some extra info: cascading dropdowns are not supported when Dataverse is the data source. It works in some cases but can give some unexpected behavior.

[@RezaDorrani]

It should work with Dataverse also. If there are issues, I would recommend posting it on the forums at powerusers.microsoft.com/ to cross check if others are facing a similar issue.

Your explanations are crystal clear - like always. Great thanks for all your fantastic videos. I was able to reproduce all the steps with a blank power app. And it works perfectly. It also works (kind of) with a customized edit form for one of my Sharepoint lists. But for the past couple of hours I fail to fix the problem, that all entries in the drop-down control are "invisible" (no text displayed). The selected value from a drop-down is correctly saved to the Sharepoint list though. Has anyone ever experienced this problem?

[@RezaDorrani]

Thanks for watching and liking the videos. I have not experienced the mentioned issue, hence not sure.

[@nabiledelbi5502]

I found the answer to my problem: In my power app settings I switched to the modern controls. These apparently do not fit to the steps described in this video. But I can switch back and forth to classic and modern controls, whatever I need to add to my form. And then everything works like a charm. Thanks again to Reza for these excellent videos.

Thanks Reaz, Very helpful. One question I had was can we make the cascading drop-down combo box as multi-select? I have a situation where the first drop down is single select and the options in the second dropdown should cascade based on first drop-down. Additionally the user should be able to select multiple options from the combo box. When I tried this, only the last selected choice is transferred to the Sharepoint on submitting the form and not the others.

Thank you for this video, Reza. It was very useful. I’m customizing a SP form in PowerApps. Within this form, I need 3 cascading dropdowns. I had to create a custom card and add a drop down to it for these cascading drop downs because the form is very long and text label kept floating up and down the page as I scrolled. I created the cascading drop downs successfully and they appear on the form, but the selections will not save to the form. I’m sure it’s because the data source for the dropdowns is from a separate SP list. However, I don’t want to create a separate record for these drop downs. I want to save the information on the same record as all of the other information on the form so within the same record. Can you advise? I greatly appreciate your help!

[@RezaDorrani]

Does the video not show the formula?

[@JansoRibeiro]

Great video! but when I filter dropdown2 based on dropdown1 the dropdown2 is coming empty, can you tell what it can be?

[@RezaDorrani]

I will have to look at your App in action to provide guidance. I would recommend posting your issue/query with screenshots on the forums at powerusers.microsoft.com

Hello Reza. Your tutorial is very interesting and well done. I have followed the different steps. I use an Excel file online and I have the same kind of problem Marialison Iriarte mentioned in the comments below : when I open the app on my computer, I have an error message indicating : Requested operation is not valid. Server response : failure of tableau 2_2 : Expression "Référence eq null" is not supported. Tableau 2_2 is my data source and Référence the first column of this table. It seems the message appears only when I use the icons >, pencil and + for the first time, then using the app it doesn't appear anymore, and data are well saved in the Excel file. Do you know why this error message appears ?

[@RezaDorrani]

I'm not sure about this. I will have to look at your App in action to provide guidance. I would recommend posting your issue/query with screenshots on the forums at powerusers.microsoft.com

@@RezaDorrani Thank you very much Reza ! I followed your advice : I've been on the forums and I found that someone had exactly the same problem as me. As an answer it was suggested to use to a SharePoint list instead of an Excel table as the data source. I've tried and it solved my problem 🙂. Thank you again

@@srainstruments45 Glad to know the issue is resolved.

Hi Reza, any video you have for SQL Database for Cascading dropdown. Much appreciated.

[@RezaDorrani]

I do not

[@iggyguajardo3463]

Great video. Question.. how can I have the cascading drop downs reset to blank outside of the form control once someone hits submit? Everything I’m finding online only works in a form experience.

[@RezaDorrani]

You should be able to use the reset function on controls. I did 2-3 videos on cascading in which I may have covered scenario outside forms.

[@MuaviaOne]

Great video... Good Job. Thank you very much. Question: What to do If I have two drop down lists with Employee ID & Employee Name and when I select Employee ID the "Employee Name" should be displayed accordingly.

[@RezaDorrani]

Depends on how the data from dropdowns is being stored in your backend system. I will have to look at your scenario in action to provide guidance. I will recommend posting your query with screenshots on the forums at powerusers.microsoft.com

[@mkavo]

Hi Reza, say you wanted to also set ur Title column text with some default text based on Country selected, and then also allow the user to append that text in the Title field and save to form, how best to go about it? seems to be very tricky to do. you can't use the dropdown as default text because each time you edit the form the Title value would flip back to that dropdown value which would be incorrect. Would only work if the Title text column was View only.

[@RezaDorrani]

Not something I have tried so not sure

[@mkavo]

@@RezaDorrani - a challenge for you so? , its a very typical scenario to have placeholder text presented based on predefined values that also allows users to edit and save..

[@RezaDorrani]

@@mkavo I have not come across this scenario at work and hence not attempted it.

[@muru4541]

Thank you Reza

[@RezaDorrani]

Your most welcome

[@austennis6759]

now which method do I choose and why? :) but more importantly, is it possible to make it so that if for some reason there is no internet connection, it will store the changes locally & then upload/submit the changes when the connection returns?

[@RezaDorrani]

Which method and why? You mean form control vs Patch function? sharepains.com/2020/06/19/patch-vs-submitform-vs-update-power-apps/ If no internet connection, then you need to handle offline storage of data. docs.microsoft.com/en-us/powerapps/maker/canvas-apps/offline-apps

How do I import Power BI table data into a dropdown on Power Apps? Your help will be awesome.

[@RezaDorrani]

Check my videos on power bi and power apps.

[@EmelineRobidou]

Is there a way to search a drop down box? I have over 300 medications that I have to scroll thru in my drop down. Thank you for great videos and sharing your knowledge.

[@RezaDorrani]

Drop down does not have a search option. Combo box has but it has limits as well. Check kzbin.info/www/bejne/sIGwYYRraLFmqacsi=cAy29ap1pIRee_7b

[@LadyRoseCas]

Thank you, Reza! May I ask how to fix if the Dropdown Properties Value only has Value, Result is not available.

[@RezaDorrani]

I have not come across this issue & hence not sure what the resolution is. I recommend posting your issue/query with screenshots on the forums at powerusers.microsoft.com

[@RuchiShah-eu3nf]

Hello, You are making great videos and very helpful. I got a requests many time, Would you be able to create video for Cascading Combo Box (Multi Selections for Region, Country, State). It would help many users . I see a lot of requests or tickets online but no one is able to solve or respond it to those ticket.

[@RezaDorrani]

I make videos when I receive multiple requests on a topic. Every 6 months I ask subscribers for topic suggestions on Community Tab of my channel. Most voted topic ideas get added to my backlog. Make sure to suggest this idea whenever the next topic suggestion post is out.

[@PratikSoni28]

Hi @Reza, Thank you so much for this video. One additional query I have here: Is it possible to achieve this in a LookUp fields. e.g. In particular this case - how to achieve this if Country and State would be LookUp fields?

[@RezaDorrani]

Maybe I showed lookup in this video kzbin.info/www/bejne/f4iogqp9gciKbbM

[@PratikSoni28]

​@@RezaDorrani Thank you for this very quick response.

[@TracyOsimowicz]

Great video. Ran into a BIG issue though because my data source has more than 500 rows, and since the Distinct( ) function is not delegable (can't pull more than 500 rows), I can't use this function to get my dropdown values distinct. Does anyone know a workaround with functions that ARE delegable for this?

[@RezaDorrani]

Distinct is not a delegable data source with SharePoint. You can change delegation limit to max 2000. I will recommend posting your query on forums in case someone has a solution for this. powerusers.microsoft.com

[@TracyOsimowicz]

@@RezaDorrani Good point. Sadly, my data is 3000+ rows so changing the delegable project parameter won't get me there either. I will make a post where you recommend.
