How to add checkBox for variables group with tabPanel in R shiny

.Hi, I need help in adding variables checkbox in r shiny within the tabPanel. I have already developed an r shiny app, in which on one of the page the data is displayed on the basis of some filterers and keywords search box.

So, I want to include one checkbox group of variables for the uploaded file. I saw some of the solution but, non of them is based on tabPanel. Is it possible to have variable checkBox with tabPanel and how to place this under UI and SERVER. Also, as rest of the development is done so, would like to have solution with tabPanel if possible. Thanks

Tried adding the checkBoxInput but with not working with tabPanel and disturbing the current tabPanel
