Support simple multi selectbox field

Notice: This plugin is unmaintained and available for adoption.


This plugin treats pseudo multiple select values with the ticket custom field. See below for an example. It requires Trac 1.0 or higher, since it uses the list format of text type. See also TracTicketsCustomFields.

Key features:

  • Provide simple multiple select values field.
  • Compared to other alternatives, this plugin is intended to be simple and light weight, easy to use.

Revert selected multiple values:

Reverting multiple select values during editing is not possible (confirmed for version 1.0.2). To use Trac's revert function, you must apply a patch included in the source distribution:

$ cd path/to/trac
$ patch -p0 < patch/support-multipleselct-for-reverthandler-trac10.patch
$ restart Trac

This plugin was inspired by MultiSelectFieldPlugin, which is a good choice, if you are looking for a more feature-rich selectbox.
