The component `Columns` is a very simple alternative to `j-Layout` and `j-Layout2`. With this component you can set columns with 100% height by your needs.


__Configuration__:

- `parent {String}` can contain `parent`, `window` or jQuery selector for the `closest` method (default: `window`)
- `margin {Number}` add margin to `height` (default: `0`)
- `marginlg {Number}` adds margin to `height` for `LG` display (default: `margin`)
- `marginmd {Number}` adds margin to `height` for `MD` display (default: `margin`)
- `marginsm {Number}` adds margin to `height` for `SM` display (default: `margin`)
- `marginxs {Number}` adds margin to `height` for `XS` display (default: `margin`)
- `noborder {Boolean}` disables border (default: `false`)
- `fontsize {Boolean}` enables percentual font-size according to the size of rows (default: `false`)

__Methods__:

- `SETTER('columns/refresh')` - reloads all `section` and sets sizes
- `SETTER('columns/add', size, html_node)` - adds a new column and performs refresh

__Good to know__:

Each column must be wrappend in `<section>`, try to understand from example.

__Attributes__:

- `data-size` contains a size of section `LG,MD,SM,XS` --> in pixels or percentage, example: `200,200,200,0` (`0` means hidden)
- section without `data-size` attribute will be counted from the residual value

Use it with `<ui-component name="columns">`. When the component is not loaded yet, jComponent downloads it on first use from the address in `DEF.fallback` (the Componentator CDN by default). Author: Peter Širka. Source: the Componentator components repository, MIT license.
