Hi @Anonymous ,
Could you please share a bit more about your scenario?
Do you want to change the Title field within the Edit form into a Dropdown box with available options?
Based on the needs that you mentioned, I think the PowerApps Edit form could achieve your needs. I have made a test on my side, please take a try with the following workaround:
On your side, you please go to your Edit form, then select the Title Data card in your Edit form, then click Edit Field in right panel (Step 2). Within the expanded Fields list, select the Title field, then change the Control Type to "Allowed Values".
Please check the following GIF screenshot for more details:
After that, you could specify available option values (table value) within the Items property of the Title Dropdown box to populate the Title Dropdown box. e.g. Set the Items property of the Title Dropdown box to following:
["PowerApps", "Power BI", "MS Flow"]
Best regards,
