Best way to do a split pane in HTML [closed]

Answer 1

A good library is Shield UI - you can take a look at their flexible Splitter widget and the rest of the powerful components the framework offers.

Answer 2

One totally different approach is to put things in a grid, such as ui-grid or Kendo's grid, and have the columns be resizable. A downside is that users would not be able to resize the rows, though the row size could be set programmatically.
