Binding dropdown to another entity

[SnehaPatil]

Hi,

How can I bind the values of another entity to a dropdown in powerapps portal?

You need to create the relationship between the entities and the data will automatically get populated.

Hi@SnehaPatil,

Based on the issue that you mentioned, do you want to retrieve data in the entity list from the Dropdown in the Portal?

Could you please share a bit more about the scenario, is it in your Dynamics365?

If you want to repopulate the dropdown on a form in CRM Portals, I think the best solution is to use Entity Form Metadata.

To achieve this, you should add a lookup field in your account form.

Select a type to Attribute, and choose your organization lookup field, in my scenario, I use the custom field on the case form. 

And choose the Control style you need.

As an alternative solution, you could consider using JavaScript. Here is a user having a similar problem with you:

Hope it could help.
