Bootstrap Icons adp:icons can be used on ADP pages with
<adp:icon name="NAME" title="..." style="..." class="...">
The last three arguments are optional. Bootstrap Icons defines in version 1.8.1 more than 1,600 icons. When installing Bootstrap Icons, all of these are usable independent of the style of the site.
However, when one wants to keep e.g. some subsites in Bootstrap 3 and others in Bootstrap 5, and the classic Bootstrap 3 look-and-feel should be kept, and the identical markup should adapt its Look-and-Feel depending on the subsite theme, there are some restrictions. OpenACS supports the icon sets "classic" (old-style gif/png images), "glyphicons" (Part of Bootstrap 3), "bootstrap-icons" (usable for all themes), and "fa-icons" (usable for all themes). Some of the icon names are usable via adp:icon for all OpenACS icon sets, some of these can be used without further mapping as replacement of the gyphicons of Bootstrap 3.
The names which can be used for all icon sets are called "generic", since for these, a mapping from the specific icon set to the generic name exists. See below for lists of names and contexts, where these can be used.
Defined generic names for adp:icons,
working with icon sets
"classic",
"glyphicons",
"bootstrap-icons", and
"fa-icons". This means that the same
name can be used in the markup. When switching the themes/iconset,
different icon sets are used without the need of rewriting any markup. These icons are
displayed here in the currently defined icon set @iconset@.
