i have create a Repeating Group of “Category” with Input showing their names.
also enable user to quickly modify the names of category in 1 click.
My Problem:
How to setup the logic in the workflow?
So, when user click the submit button, it will capture the new name ( or all name ) and applied into the category?
STEP 1:
Create a Repeating group displaying all your “Categories”
STEP 2:
Insert input fields. Set each “CategoryName” to be initial content.
NOTE
Data should be either auto-binding or you’ll need SAVE button next to each input field to make changes. Save Button outside the Repeating Group won’t work. At least, I don’t know how to make it work.
Let me know if this helps.
