How to update FastListTemplate main based on the type of chart selected

My use case is pretty generic;

Based on a Select widget value from FastListTemplate sidebar, I want to display the content in the template.main area. Also, on the landing page, I am already displaying an image and some text. So on_click or param.watch of the Select button should generate charts and replace the existing template.main.

I tried replacing it, however, once the template is rendered I don't see it changing when I select a different value in the selector.

Please suggest or point me to any resources that can help me here, many thanks!

Solution

  • The template can not be rendered again, but we'll have to wrap the content in a Column or Row and update the content inside the Column or Row.

    append_col = pn.Column(old_chart)
template.main.apend(append_col)

    and to update it

    append_col[0] = new_chart
