An easier way to accomplish this, if I understand your usage correctly, would be with a custom state.
For example: You have a repeating group with fields you would like the user to be able to edit, such as a customer’s data.
And we want to be able to edit customer data, and then save it.
What we’ll do is construct our repeating group with the appropriate fields for our data type. We’re going to use INPUT fields, rather than TEXT elements.
Then, we’ll style the inputs so that they look like text elements. In the element’s settings, we’ll also set these input fields to “This Input is Disabled” by default.
Next, we’re going to create a custom state and call it “Edit Mode”, which will be a “Yes/No” Value. Yes being editable, no being not editable. It doesn’t matter which element you set the custom state on, but setting it on the repeating group is probably the easiest.
Now, we’re going to set some conditions on the various elements, so that they will change depending on the “Edit Mode”.
Set the conditions of the Input elements to "When [repeating group’s] “Edit Mode” is Yes, and the “Property to Change” will be “This input is disabled”. Set that to no, so that it will be active for editing. For a little extra styling, you can also change the background color of the element to make it a little more noticeable by the user. Set an alternate state for when “Edit Mode” is no, and make the input disabled.
You can do the same with the “Edit” button you made, so that it becomes a “Save” button when in edit mode.
Now, in your workflows, you will create two separate flows for each state. One for what happens when it’s yes, the other for no.
So, when the button is clicked, and the repeating groups edit mode is “yes”, we will “make changes to a thing” which is the current cells customer, and change the fields to the value of the input elements.
The alternate will be when the button is clicked, and the repeating groups edit mode is “no” we will set the state of the repeating group to “yes”. So, when edit mode is “No” set state to “Yes”. This enables all the conditions to make the fields editable.
This way, the user will be able to edit all data in-line, without creating separate groups.
