Filter option to retrieve part/section of the Webpage Objects

[nitfeu]

I am lacking experience and knowledge in using this plugin in Chrome to customise it for my purpose and hence need some help to figure out if some filter operation is possible with this tool.

Requirement & Problem: My page is so complex that this plugin generates 5000 lines of code from just one page with the default filter available. But I need to filter and retrieve only the page objects from the code block/ division block (a table) with HTML id = "navi_tree".

Solution needed: What should be the filter criteria under 'Root Selector' in the options window? Or is there any other filter method that works for my requirement.

Note: If a Guideline document is available for this plugin, kindly share it's web-link for understanding and usage purpose.
