I'm trying to give default value for drop down from gallery selected text.

I added data source as Name for drop down and for this default name should be displayed from gallery

I tried doing look up but it's not showing selected name in gallery

On the OnSelect of the Icon or button inside the Gallery Set a variable;
Set(MySelected, Gallery1.Selected.YourColumnForDropdown)
Then in the Default of the dropdown put:
MySelected

Hi @SumanKoduri ,

Step1: Ensure that the gallery items are part of your dropdown list items
Step2: Set the default value of the dropdown with variable (ex: varGalSelectedTitle)
Step3: update the variable value as part of the gallery selected property
ex: UpdateContext({varGalSelectedTitle:Gallery2.Selected.Title});

See the below for your reference:

Note: if this helps mark it as the solution.

Krishna

Hi @SumanKoduri ,

First thing first sorry for the late reply.
Here is the working model to show the default dropdown value with the selected ID in the gallery:

And the formula for the dropdown is as follows:
for items:
Distinct('Employee Details'.Title,Title)
for Default value:
LookUp('Employee Details',Title=Gallery5.Selected.Title).Title

Hope that works, please let me know if you see any further issues.

Regards,
Krishna
