Hi,
The example provided by Sefoudine FIDAHOUSSEN must do you trick
see the part below extracted:
<pdm_if "$args.category.sym" == "CategoryName">
<pdm_macro name=dtlCheckbox attr=attribute hdr=header>
</pdm_if>
in your case you will just specify the tab to hide instead of the checkbox. that'it
like in the example below for the properties tab
<pdm_if "$args.category.sym" == "CategoryName">
<PDM_MACRO name=tab title="Properties" file="xx_prop_tab.htmpl">
</pdm_if>
Hope this help.
