List too long on the left

[miraks31]

Hi,

First, thank you for pivottable because I use it in a project and it works very well.

Sometime, the end user has to treat a data set with many columns (>300) and so, the pivottable is very high with a very high left area where you can select the attributes you want. This is very difficult to select on attribute by scrolling down, drag and drop on the top of the table.

When the number of columns is greater than 20, is it possible to have a "search" input field on the top of this list to filter all the attributes containing the entered string ?

Thank you in advance for your answer.
