How to build a dropdown in UiPath apps

[shetanshudhar]

How do we build a functional dropdown using UiPath apps.
I want to build multiple dropdowns in my app page where all have static options.
Any pointers would be highly appreciated.
@loginerror @Srini84 help please.

Hey @shetanshudhar

You can have three dropdowns on the page with values.

Based on dropdown element events you can make others available or not.

Thanks

@Nithinkrishna how do we put values in the drop-down? It asks me for an input list and a column. Can you show me via screenshots or any link to any tutorial directly creating dropdowns in UiPath apps will be helpful.

Hey @shetanshudhar,

1. Create a process with an out argument in main workflow of type string array. Add it in your app.

2. Go to your dropdown element and map the process out argument to the list source.

3. Go to the page event - in which the dropdown is present

4. Edit Rule & Use Start process action to initiate your process.

That’s it you are good to go.

Once you run the app, you can see your dropdown with populated values

Adding to it, You can have any number of arguments and map it to various dropdowns accordingly.

Thanks

@Nithinkrishna so do we need to run background processes having string array out arguments via bots every time we want to populate values in a dropdown in UiPath apps?

[Nithinkrishna]

Yep Right, for now that is the case.

I’m not sure if there is any progress as far as adding an easier way to populate drop-downs in Apps.

UiPath could implement this (in theory) as follows:

Link Assets to Apps. We create a text type asset and populate a csv list of key-value pairs as a string into this asset. Something like this

[(1, “Excellent”), (2, “Good”), …]

The drop down control in Apps could be enhanced to accept this asset as an input and the key-value pairs could be mapped into the drop down provided the above string is formed correctly.

The advantage here is, this arrangement could be used by humans for static assets and also Robots for Dynamic assets, but there may be additional challenges if any apps are currently using that drop down control at the time!

Just a thought.

Excellent suggestion @AndyMenon! Creating static drop-downs and lists is in the works and will be in the next update for the Expressions Preview.

We also have asset integration on our backlog and will definitely look into prioritizing it.

Fantastic @evan.cohen !

Looking forward to these enhancements

Thanks!

I see that they introduces static dropdowns:
Enable this setting in General tab of the App

And start using functions:

Hi @Oana_Georgiana_Vasile

this is my case:

Can you help me, why is it showing:

Thx and kind regards,
Vanja

[Oana_Georgiana_Vasile]

Put the list under List Source. You put it under Tooltip.

[VanjaV]

Thank you @Oana_Georgiana_Vasile , I did not have that option available.

Hi, @Oana_Georgiana_Vasile

Do you have any suggestion how to solve it with “Other…”?

Thx and kind regards,
Vanja

[Oana_Georgiana_Vasile]

I am not sure if I understood correctly that you need to see in the dropdown the value entered by the user in Other field, but here it is a solution:

1. Go to Other… text field and create a variable where to store its value. You can also use the same variable used to store drop-down value
   

   
   
   

2. drag and drop it in the Value Binding
   

3. Go to drop down on List Source and drag and drop the Value of your Text Field. My text field is named DemoText.

[VanjaV]

Hi @Oana_Georgiana_Vasile

Thank you very much

I solved it that way, and it is working:

User selects Other in dropdown and enters it into text field “Other…”.
When moving mouse to another field, UiPath App displays content of “Other…”
in dropdown field:

Kind Regards,

Hi guys, I have an entity named Processes. And now I wanna add a dropdown control with the list of process names from that entity. How can I do that?
=List(Processes.Process Name) doesn’t work

[Nithinkrishna]

Hey @tranthao240495

Here is the way of doing it, Hope this helps.

1. Pass only **Data Entity** table name in **List Source** field
2. Pass the **Column** name you want to populate in the dropdown in **Column** field

Thanks

Hello Guys,

How can I pass the Default value as List item 1.

In my case I created List variable and passing the values. I want to display in drop down default value as first item from the List.

How can I achieve this?
