the sidebar is not getting displayed to full height.

Hello,
It may be easier for us to help you if you give us access to the page. I can't determine the issue just from a screenshot.
Thanks!
I'm having the same problem.When I resize the window by double clicking the title bar the sidebar height is incorrect and I've been trying all day to fix it but still no luck! :(

@niks-codificador Did you fix it?
@FalconDev91 not yet. Even I banged my head to get it fixed.
@FalconDev91 I figured the error out. Yeah it quite late, like after months.
Put sidebar code in wrapper class. See below
Hope it helps you. it helped me. Thanks @almasaeed2010 for this amazing template.
I'm still having this issue on 2.3.3, putting the sidebar in wrapper class does not work for me:

Share your code so that I could help you with!
I managed to do it using jQuery. Simply get the height of the current document once it is loaded and then assign that height to the sidebar.
jQuery(document).ready(function($){ $('.main-sidebar').height($(document).outerHeight()); });
In my case the sidebar has a class of main-sidebar. You can change it to your value.
@nikhilshirsath1993 did you fix it?
I know this is an old thread, but just in case someone else comes across it. I found the problem was that if the page dynamically changes height (say an ajax table loading) then the main-sidebar doesn't adjust it's height. So I took andresbello's solution a step further and watch for document height changes and then adjust the sidebar height appropriately:
function onElementHeightChange(elm, callback) {
var lastHeight = elm.clientHeight, newHeight;
(function run() {
newHeight = elm.clientHeight;
if (lastHeight != newHeight)
callback();
lastHeight = newHeight;
if (elm.onElementHeightChangeTimer)
clearTimeout(elm.onElementHeightChangeTimer);
elm.onElementHeightChangeTimer = setTimeout(run, 200);
})();
}
onElementHeightChange(document.body, function () {
//alert('Body height changed');
$('.main-sidebar').height($(document).outerHeight());
});
