In InDesign, I have some filled text boxes, sized by columns, with the one on the left being three columns wide.
The wide text box is most likely to contain the most text (it's an invoice template). I will use the 'Fit frame to content' button on the Selection Tool toolbar for automatically vertically resize it to fit the containing text.
How do I make the other three smaller text frames automatically adjust to the same height as the big (and longer) text box?
