: This class is defined if a tag does exist as a tiddler
!!! Defining the class
To define the `tc-tag-missing` class a stylesheet tiddler needs to be created. The default font-style for missing tiddler links is //italic//, so it's used for the example code below. Eg:
''title:'' `myTagsStylesheet`<br>
''tag:'' `$:/tags/Stylesheet`
<<copy-to-clipboard-above-right src:"""
.tc-tag-missing {
font-style: italic;
}
""">>
```
.tc-tag-missing {
font-style: italic;
}
```

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 $name=".example" n="3" eg="""<$list filter="[tag[HelloThere]]">
<$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 $name=".example" n="4" eg="""<$list filter="[tag[HelloThere]]" counter="transclusion">
<$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 $name=".example" n="5" eg="""<$list filter="[tag[HelloThere]]" variable="transclusion">
<$macrocall $name=".example" n="6" eg="""<$list filter="[tag[HelloThere]]" variable="transclusion">
* <$link to=<<transclusion>>/> is tagged with: <$list filter="[<transclusion>tags[]]"> <<tag>> </$list>
