<$macrocall $name=".example" n="1" eg="""<<tag>>"""/>
<$macrocall $name=".example" n="2" eg="""<<tag Concepts>>"""/>

The Following tag can be shown with a font-style: //italic// if the corresponding stylesheet exists. See: [[tag Macro]]

<$macrocall $name=".example" n="3" eg="""<<tag "Does not exist">>"""/>

If a [[list widget|ListWidget]] generates multiple tag macros for the same tag, clicking any of them opens dropdowns on all of them, as in the example below. This is usually unwanted.
<$macrocall $name=".example" n="4" eg="""<$list filter="[tag[HelloThere]]">

* <$link/> is tagged with: <$list filter="[<currentTiddler>tags[]]"> <<tag>> </$list>

</$list>"""/>

Adding the `counter="transclusion"` attribute to the list widget that generates multiple identical tag macros causes each of them to be identified as a unique one. Clicking on any of them opens only a single dropdown.
<$macrocall $name=".example" n="5" eg="""<$list filter="[tag[HelloThere]]" counter="transclusion">

* <$link/> is tagged with: <$list filter="[<currentTiddler>tags[]]"> <<tag>> </$list>

</$list>"""/>

A slightly more performant option is to use the `variable="transclusion"` attribute in the list widget. In this case, the variable `<<transclusion>>` has to be used inside the list widget instead of the `<<currentTiddler>>` .
<$macrocall $name=".example" n="6" eg="""<$list filter="[tag[HelloThere]]" variable="transclusion">

* <$link to=<<transclusion>>/> is tagged with: <$list filter="[<transclusion>tags[]]"> <<tag>> </$list>

</$list>"""/>
