      workflow and allows you to quickly ${this.helpActions} all nodes within the group.</p>

      <ul>

        <li>

          <p>

            <strong>Properties.</strong> You can change the following properties (by right-clicking

            on the node, and select "Properties" or "Properties Panel" from the menu):

          </p>

          <ul>

            <li><p>

              <code>${PROPERTY_MATCH_COLORS}</code> - Only add groups that match the provided

              colors. Can be ComfyUI colors (red, pale_blue) or hex codes (#a4d399). Multiple can be

              added, comma delimited.

            </p></li>

            <li><p>

              <code>${PROPERTY_MATCH_TITLE}</code> - Filter the list of toggles by title match

              (string match, or regular expression).

            </p></li>

            <li><p>

              <code>${PROPERTY_SHOW_NAV}</code> - Add / remove a quick navigation arrow to take you

              to the group. <i>(default: true)</i>

              </p></li>

            <li><p>

              <code>${PROPERTY_SORT}</code> - Sort the toggles' order by "alphanumeric", graph

              "position", or "custom alphabet". <i>(default: "position")</i>

            </p></li>

            <li>

              <p>

                <code>${PROPERTY_SORT_CUSTOM_ALPHA}</code> - When the

                <code>${PROPERTY_SORT}</code> property is "custom alphabet" you can define the

                alphabet to use here, which will match the <i>beginning</i> of each group name and

                sort against it. If group titles do not match any custom alphabet entry, then they

                will be put after groups that do, ordered alphanumerically.

              </p>

              <p>

                This can be a list of single characters, like "zyxw..." or comma delimited strings

                for more control, like "sdxl,pro,sd,n,p".

              </p>

              <p>

                Note, when two group title match the same custom alphabet entry, the <i>normal

                alphanumeric alphabet</i> breaks the tie. For instance, a custom alphabet of

                "e,s,d" will order groups names like "SDXL, SEGS, Detailer" eventhough the custom

                alphabet has an "e" before "d" (where one may expect "SE" to be before "SD").

              </p>

              <p>

                To have "SEGS" appear before "SDXL" you can use longer strings. For instance, the

                custom alphabet value of "se,s,f" would work here.

              <code>${PROPERTY_RESTRICTION}</code> - Optionally, attempt to restrict the number of

              widgets that can be enabled to a maximum of one, or always one.

              </p>

              <p><em><strong>Note:</strong> If using "max one" or "always one" then this is only

              enforced when clicking a toggle on this node; if nodes within groups are changed

              outside of the initial toggle click, then these restriction will not be enforced, and

              could result in a state where more than one toggle is enabled. This could also happen

              if nodes are overlapped with multiple groups.
