My suggestion is to create a module with that list and create one line item with "Text" formatted and bring in the Name into that line item by writing Name(Item('')) if it is a normal list or Display Name.List if it is a numbered list. Then put Sorting on the above created line item either in Ascending or Descending order based on your requirement. Please have a quick look at the below screen shot.
But if i a have more properties and the data is coming through other integrations.And after sorting in the module i need to import to the list. But after some days if the list get updated with other names and again we need to run the import action again. These way the model size increases more. Is there any other way to sort the items in list.
Step 1: Create a List called "Alphabetical Order" and create all the 26 characters as a list items with code starts from 0 to 26. ( Note :This will be a one time actvity) You can use this for any list that needs to be sorted.
Step 2: Create a line item in your module(Would always prefer because of Model performance and don't create properties) and it should be number formatted. The module should have the dimension of the list that you needs to get it sorted. Then write the below formula and sort that accordingly (Basically create relation between your list and Alph.. List and convert that to number) .
So in this way you can do your sorting permemantly without any increase in Model size as well. You can use that list "Alphabetaical Order" for whatever list that you want to sort.
Thanks and let me know if you have any concerns. I hope this would be helpful!! :)
