Tab Placeholder not support granite:class and granite:data [Content Fragment]
To add any custom class and attribute to the dialog element we use granite:class and granite:data respectively. It works fine for Coral Textfield, Select, etc. I tried to implement the same for Tab Placeholder, but class and attribute not available on HTML for Tab.
<_x0031_689938985967 jcr:primaryType="nt:unstructured"
granite:class="tab-container"
sling:resourceType="dam/cfm/models/editor/components/tabplaceholder"
fieldLabel="Blog Post"
listOrder="21"
metaType="tab-placeholder"
name="placeholder"
renderReadOnly="false"
showEmptyInReadOnly="true"
valueType="string/tab" />
Is there any other way to add custom class and attribute to the Tab Placeholder?
