So from what your saying how can achieve what I explained I wanted to do? I see websites all the time allowing users to select which records to update using a checkbox. so not sure why it cannot be achieved?
In case I have explained myself in a way that makes no sense I am attaching a screenshot that hopefully illustrates what I want to code :)
So as you can see Admin selects desired option (static content) from select box) then they will tick desired checkboxes and the click the save submit button and this will update all the checkboxed records with the updated order progress.
The feedback you have given me gives me the impression that this task cannot be done??
