Hi @Kumar9024021 ,
Based on your description, I think what you want is a combination of gallery, editform and display form.
Firstly, in gallery form, you could view all the items of the list.
You could set the arrow button to navigate to edit form screen.
Then when you click the arrow button, you will jump to the edit form and linked with the item that you selected in gallery.
Also, you could also filter,sort, search in the gallery.
Key points:
use gallery to display, set gallery's Items to filter,sort, search formula, set arrow button's OnSelect to navigate function.
Secondly, in edit form screen.
Set the edit form's Item to gallery1.Selected.
Then the edit form will display the item that you selected in the gallery.
Insert a submit button, set its OnSelect: SubmitForm(Form1);Back()
Then after you click the button, the data will be submitted and you will come back to gallery screen.
Thirdly, in display screem.
Set the display form's Item to gallery1.Selected.
Then you could view the item that you selected in the gallery in details.
The app will look like this:

Here's a doc about this kind of app in details for your reference:
