 Limit of pages to be rendered. `0` shows all pages (default). `-1` will hide numeric pages and leave only arrow navigation. Any positive integer (e.g. `2`) will define how many pages should be shown on either side of the current page when only a range of pages are shown.

+* `Boolean` (optional)
+
+When `true`, the pagination component will keep the same length regardless of the position of the page number. This is useful when you want to keep the pagination component always the same size and not vary at the first or last pages. It does uses the `limit` to determine the length of the pagination component.
