title: Is it possible for dropdown filter of jquery tablesorter to distinguish multiple values within the same cell?
body: <p><a href="https://mottie.github.io/tablesorter/docs/example-widget-filter-custom.html" rel="nofollow">https://mottie.github.io/tablesorter/docs/example-widget-filter-custom.html</a> gives a few examples - First Name column filters by cell content being the filter options, while City and Total have predefined options as filter values.</p>
  
  <p>Sometimes, we need to use the cell contents as filter options because we don't know all the possibilities to use the predefined options, but these cell contents might contain multiple values. Imagine a column Category which lists one or more categories the row is associated to. They could be separated by a comma, new line, br tag, etc. How can we add a dropdown filter at the top listing each separate category without having to list them all? If we use the automatic dropdown, we get the cell contents as filter options: e.g. "Loan, Insurance" will be the filter option rather than two options - "Loan" and "Insurance". If these are separated by break tags, things start to look even uglier.</p>
  
  <p>Thanks!</p>
