It sorts at the parent level and then inside the respective parents, it shorts child rows within that parent which is great.
My requirement is for making a row static so that row should not sort and maintain its index within the parent.
There is static row widget: https://mottie.github.io/tablesorter/docs/example-widget-static-row.html But it will lock the static row in its position/index in the table including parent index.
So suppose, if I mark 'Caïro'(index=2, row=3) as static inside 'Africa -> Egypt' then on sorting, above widget will show 'Caïro' on row 3rd only and hence 'Africa -> Egypt' will not have 'Caïro' so 'Caïro' moves out from parent.
And my requirement with above example is that, 'Caïro' position/index should be maintained at index 0 inside Africa -> Egypt.
So after sorting as per the second screen below, 'Caïro' should be at index 0 and should be ignored in sorting and 'Luxor' should be sorted from index 1 onwards with rest of the rows(if present).
If anyone can help me on this, it would save my day. :)
