I am developing an web app on AngularJS, which has similar functionality to Dev HTTP Client and right now I have to divide my web-ui into 2 parts and make the first one resizible with the element like this one:
so I could just move it up and down and the content inside the element gets resized.
Does anyone know how can I develop such element? Please, point me to the solution, provide some links, articles. Every useful answer is highly appreciated and evaluated.
Thank you.
