Layout with sticky sidebar on the left and scrollable content on the right-CodePudding

How do I make a two column layout, where the left column is my menu and is locked (sticky? fixed?) so when you scroll vertically depending on the content height in the right column, the menu stays.

Second thing, I guess i have to use javascript for (vanilla, no jquery) is so make the columns resizable. with the css I would use 'cursor: col-resize' but the JS i have no clue.

.row {
  display: flex;
}

.column {
  flex: 50%;
  padding: 16px;
}

.one {
  background-color: tomato;
  min-height: 100%;
}

.two {
  background-color: #33a8ff;
  height: 5000px;
}

html,
body {
  height: 100%;
  margin: 0;
}

<div >
  <div >
    <h2> column #1 </h2>
    <p>menu items</p>
  </div>
  <div >
    <h2>column #2</h2>
    <p> Some contents in column 2 </p>
  </div>
</div>

You could do it like in my snippet below. Both columns have height: 100%;, the right one has overflow-y: auto to show a scrollbar only if necessary and scroll the contents inside that column:

* {
  box-sizing: border-box;
}
html,
body {
  height: 100%;
  margin: 0;
}
.row {
  display: flex;
  height: 100%;
  background-color: #33a8ff;
}

.column {
  flex: 50%;
  padding: 16px;
}

.one {
  background-color: tomato;
  height: 100%;
}

.two {
  height: 100%;
  overflow-y: auto;
}

<div >
  <div >
    <h2> column #1 </h2>
    <p>menu items</p>
  </div>
  <div >
    <h2>column #2</h2>
    <p> Some contents in column 2 </p>
    <p> Some contents in column 2 </p>
    <p> Some contents in column 2 </p>
    <p> Some contents in column 2 </p>
    <p> Some contents in column 2 </p>
    <p> Some contents in column 2 </p>
    <p> Some contents in column 2 </p>
    <p> Some contents in column 2 </p>
    <p> Some contents in column 2 </p>
    <p> Some contents in column 2 </p>
    <p> Some contents in column 2 </p>
    <p> Some contents in column 2 </p>
    <p> Some contents in column 2 </p>
    <p> Some contents in column 2 </p>
    <p> Some contents in column 2 </p>
    <p> Some contents in column 2 </p>
    <p> Some contents in column 2 </p>
    <p> Some contents in column 2 </p>
    <p> Some contents in column 2 </p>
    <p> Some contents in column 2 </p>
    <p> Some contents in column 2 </p>
    <p> Some contents in column 2 </p>
    <p> Some contents in column 2 </p>
    <p> Some contents in column 2 </p>
  </div>
</div>

You could use position:sticky. But in order to see a difference, set a smaller height on the menu container.

.row {
  display: flex;
}
.column {
  flex: 50%;
  padding: 16px;
}
.one {
  background-color: tomato;
  position: sticky;
  top: 0;
  height: min-content;
}
.two {
  background-color: #33a8ff;
  height: 5000px;
}

html,
body {
  margin: 0;
}

<div >
  <div >
    <h2> column #1 </h2>
    <p>menu items</p>
  </div>
  <div >
    <h2>column #2</h2>
    <p> Some contents in column 2 </p>
  </div>
</div>
