RE: Unified Interface- Sub Area- URL- User List
Dear Shalini,
I am not a developer so I can just provide some high-level information on PCF - there are other community members that are more experienced in creating PCFs. But nevertheless, you do not need to be a developer to use PCFs in Model Driven Apps.
PCF (or PowerApps Component Framework) Controls are ProCode Components developed mostly in TypeScript and React and using the Framework provided by Microsoft to enhance functionality and usability in Power Apps. There are lots of PCF components already in Model Driven Apps that Microsoft is creating and providing by default (e.g., Autocomplete, Calendar Views, etc.)
As mentioned in my blog post above, there is a free community gallery with lots of PCF components (https://pcf.gallery) and having a quick look at it, I just found a component that seems to fit your requirement (pcf.gallery/.../ by Author: Cathal Noonan).
Following the link to the PCF gallery there is a GitHub download link for a managed solution and a quick installation and configuration note by the author.
When a managed solution is provided, you can import the PCF solution to an environment. Afterwards you need to navigate to the form where you want to include the PCF and in the classic editor you first must add a field that will only be used as a placeholder for the PCF, and you need this field to configure the control. Open then the properties of the field, navigate to the control tab and add the specific PCF control. In most cases you must then configure the PCF e.g., specify a field that will be used inside the PCF.
When the pcf is set up you need to save and publish the form and when everything works the PCF will be available in your App.
But as I mentioned in my blog post as well - I would not recommend using a PCF control in a productive environment without having a look in the source code first and test the behavior of the PCF.
You can find more information about PCF in the Microsoft docs:
