How do to save a value on component by html ID

[Guillenius]

hi, I have a collection items and into by one collection I have a input where the user put a value number. I need to save the value in the input by WF on change, but cannot find the component`s name on the WF… then I think if I put a html ID I would find the component and save the value but nothing… I am using this code to find the HTML ID:

return(document.getElementById('form1'));

but the return is null.

This is my collection fig_1

the id`s name: concatenate(“form”,context.item.index)

WF on the component by on change action:

regards!!

Select dropdown in collection list

When inputs are in a repeated element (collection list, columns ecc) you need to keep track of the values (in your case the selected values) using variables and workflows. This guide explains how to do it. This example is similar, but using checkboxes. You can adapt the sam principle to work with the select or any other input.
