How to only show the section selected in Section Widget?

[vicelover]

Hi, guys

In my site, there is a special section, for example let's name it as "Test Section", who will has many sub-sections, so the Section Widget will be look like a big list.

So, when I click the Test Section, I want to hide those unselected sections, only show Test Section and its sub-sections in Section Widget.



I had tried to do it by myself via modify the vbcms_widget_sectionnavext_page , but it seems beyond my ability. Maybe should create a new widget similiar with Section Widget but only show the selected section. So, can anyone give me a hint?

Best Regards
