To add a block to a page, simply click on "Website", in the sidebar of your Amenitiz administrator area, a submenu will appear below and you can click on "Website", from there click on the "Customize" button located at the top right of your screen.
You will arrive by default on the home page. All you have to do is click on the "Pages" button, located at the top of your screen in the horizontal bar.
A sidebar will open giving you access to all the pages of your site.
Click on the name of the page on which you want to add this block, and it will be loaded into the editor.
In the sidebar containing the page blocks, click on "Add an element".
A new sidebar will open containing the list of items available in the editor.
Click on the desired element and it will be integrated directly into the base of your page (you can of course change the order of the page blocks).
Now that the block was added to your left menu, click on it to customize the settings, content, etc:
Some blocks are only available on some specifics pages, for example the availability planning is available on the rooms pages only.
