The optional column footer is available for single- and multi-column trees, with labeled buttons or just titles (see Footers.Appearance). Each footer or button label may be left or right adjusted or centered within the column boundaries (see Footer.TextHAlign and Footer.TextVAlign). Column footers can contain graphics (see Footer.Image). Each column footer can contain single or multiple lines of text (see Footer.Text and Footers.Multiline) and a graphic.
The built-in column footers support text and one graphic for each column. All graphics must be the same height and width for all columns.
Column footers support a footer dropdown/filter button which takes up a portion of the footer.
