# float

A floating, potentially draggable user interface element.

```html
<tosi-float class="float" remain-on-resize="remain" remain-on-scroll="remain" drag>
  <h4>Drag Me</h4>
  <div class="no-drag balloon">🎈</div>
  <div class="behavior">I ignore resizing and scrolling</div>
  <footer style="font-size: 75%">neunundneunzig pixel-ballon</footer>
</tosi-float>

<tosi-float class="float" remain-on-scroll="remain" style="top: 50px; right: 20px;" drag>
  <h4>Drag Me</h4>
  <div class="no-drag balloon">🎈</div>
  <div class="behavior">I disappear on resize</div>
  <footer style="font-size: 75%">neunundneunzig pixel-ballon</footer>
</tosi-float>

<tosi-float class="float" remain-on-resize="remain" remain-on-scroll="remove" style="bottom: 20px; left: 50px;" drag>
  <h4>Drag Me</h4>
  <div class="no-drag balloon">🎈</div>
  <div class="behavior">I disappear on scroll</div>
  <footer style="font-size: 75%">neunundneunzig pixel-ballon</footer>
</tosi-float>

## Styling

Note that the `<tosi-float>` element has absolutely minimal styling. It's up to you to provide a drop
shadow and background and so on.

## Attributes

- `drag` false | true — to make a `<tosi-float>` element draggable, simply set its `drag` attribute.
- `remain-on-resize` 'remove' | 'hide' | 'remain' — by default, floats will hide if the window is resized
- `remain-on-scroll` 'remain' | 'remove' | 'hide' — by default, floats will remain if the document is scrolled

A float made by `popFloat` (menus, tooltips) has an **anchor**, the element it was popped from, and only a
scroll that MOVES the anchor (the page, or a scroller containing it) hides or removes it. Before 1.16.3 any
scroll anywhere did, so filtering a table on every keystroke (which scrolls it) closed a menu or hint list the
moment it opened. A float with no anchor still reacts to any scroll outside itself.

To prevent dragging for an interior element (e.g. if you want a floating palette with buttons or input fields)
just add the `no-drag` class to an element or its container.
