## Migrating to v0.2.5
As of v0.2.5 all methods and parameters are in camel case to respect [JavaScript Style Guide and Coding Conventions](http://www.w3schools.com/js/js_conventions.asp).
All old methods and parameters are marked as deprecated and still available but a warning will be displayed in js console. They will be available until v1.0
when they will be completely removed.
## Options
- `always_show_resize_handle` - if `true` the resizing handles are shown even if the user is not hovering over the widget
- `alwaysShowResizeHandle` - if `true` the resizing handles are shown even if the user is not hovering over the widget
(default: `false`)
- `animate` - turns animation on (default: `false`)
- `auto` - if `false` gridstack will not initialize existing items (default: `true`)
- `cell_height` - one cell height (default: `60`). Can be:
- `cellHeight` - one cell height (default: `60`). Can be:
- an integer (px)
- a string (ex: '10em', '100px', '10rem')
- 0 or null, in which case the library will not generate styles for rows. Everything will have to be defined in CSS files.
- `draggable` - allows to override jQuery UI draggable options. (default: `{handle: '.grid-stack-item-content', scroll: true, appendTo: 'body'}`)
- `handle` - draggable handle selector (default: `'.grid-stack-item-content'`)
- `handle_class` - draggable handle class (e.g. `'grid-stack-item-content'`). If set `handle` is ignored (default: `null`)
- `handleClass` - draggable handle class (e.g. `'grid-stack-item-content'`). If set `handle` is ignored (default: `null`)
- `height` - maximum rows amount. Default is `0` which means no maximum rows
- `float` - enable floating widgets (default: `false`) See [example](http://troolee.github.io/gridstack.js/demo/float.html)
- `item_class` - widget class (default: `'grid-stack-item'`)
- `min_width` - minimal width. If window width is less, grid will be shown in one-column mode. You need also update your css file (`@media (max-width: 768px) {...}`) with corresponding value (default: `768`)
- `placeholder_class` - class for placeholder (default: `'grid-stack-placeholder'`)
- `placeholder_text` - placeholder default content (default: `''`)
- `itemClass` - widget class (default: `'grid-stack-item'`)
- `minWidth` - minimal width. If window width is less, grid will be shown in one-column mode. You need also update your css file (`@media (max-width: 768px) {...}`) with corresponding value (default: `768`)
- `placeholderClass` - class for placeholder (default: `'grid-stack-placeholder'`)
- `placeholderText` - placeholder default content (default: `''`)
- `resizable` - allows to override jQuery UI resizable options. (default: `{autoHide: true, handles: 'se'}`)
- `static_grid` - makes grid static (default `false`). If true widgets are not movable/resizable. You don't even need jQueryUI draggable/resizable. A CSS class `grid-stack-static` is also added to the container.
- `vertical_margin` - vertical gap size (default: `20`). Can be:
