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.
Best Regards,
