Tagfield but only level parent dont show child tags

[gdguradio]

<category
cq:showOnCreate="{Boolean}true"
granite:class="page-tagging-inheritance"
jcr:primaryType="nt:unstructured"
fieldLabel="page.category.label"
fieldDescription="page.category.label.desc"
sling:resourceType="cq/gui/components/coral/common/form/tagfield"
autocreateTag="{Boolean}false"
emptyText="page.tag.singleSelect.emptyText"
name="./pagetagging/category"
required="{Boolean}true"
rootPath="/content/cq:tags/com/careers/category/">
<granite:data
jcr:primaryType="nt:unstructured"
cq-msm-lockable="pagetagging/category"
category-field=""/>
</category>

I have the above and it is getting the correct tags because I used rootPath to have a specific tags to use. Now I want to only show the parent tags and not the child tags .

Is this possible ? I tried using datasource but the data in datasource is not use for the tags.
I want to show only the parent like the first tag and remove the child tag for the 2nd and third tags.

Hi,

You can create a custom datasource to returm only first child tag label and values and use dropdown insteadof tagpicker, if that helps

Hi,

I create something like this ,

<tags
jcr:primaryType="nt:unstructured"
sling:resourceType="granite/ui/components/foundation/form/autocomplete"
fieldLabel="Tags"
mode="contains"
name="./cq:tags">
<datasource
jcr:primaryType="nt:unstructured"
sling:resourceType="cq/gui/components/common/datasources/tags"/>
<values
jcr:primaryType="nt:unstructured"
sling:resourceType="granite/ui/components/foundation/form/autocomplete/tags"/>
<options
jcr:primaryType="nt:unstructured"
sling:resourceType="granite/ui/components/foundation/form/autocomplete/list"/>
</tags>

and then in the crx/de i found a jsp file in the path "/libs/cq/gui/components/common/datasources/tags" which i duplicated to create my own datasource ... I just have one more question in the source code I could use somthing like 

java.util.Iterator<Tag> listChildren(Filter<Tag> filter)   

 from Filter (The Adobe AEM Quickstart and Web Application.) the only problem I have is that I am not sure how to create the Filter<Tag> filter part .. I am still looking for sample implementation but if you could point me to the right path or give an example that could help alot.

thank you

Hi,

You can check this to do it without filter

https://aemlab.blogspot.com/2018/08/searchfilter-touch-ui-dialog-dropdown.html

with filter you can try creating custom filter by extending/implementing or by adding a methode e.g.PageFilter
