So in the above screen shot I’d prefer to have ‘blue cheese’ keep the same height but change the width and just cause the RG to have rows with different number of columns .
Deselect “This repeating group has a fixed width” and select “Allow more than one column when stretched”.
Add an ID Attribute to the RG (I’m using “tag_rg” as my id).
Add a text element inside the RG’s one cell that is the same width as the cell. Add your dynamic text content to this text element and style it however you prefer.
Add the following code snippet to your Page HTML Header found at the bottom of your page’s element editor dialog.
Can do it with HTML and get better control over design
The new responsive engine makes it even easier and would use the repeating group with other elements which is better than HTML method as it is easier to control conditionals and trigger workflows. Plus can have more than just text such as images or icons being contained in the tag.
