# Read-only Mode

In this part we want to consider read-only mode in the context of 4 situations:

1. [Read-only mode for the entire scheduler](guides/readonly.md#read-only-mode-for-the-entire-scheduler);
2. [Read-only mode for the entire lightbox](guides/readonly.md#read-only-mode-for-the-entire-lightbox);
3. [Read-only mode for a lightbox's section](guides/readonly.md#read-only-mode-for-a-lightboxs-section);
4. [Read-only mode for specific events](guides/readonly.md#read-only-mode-for-specific-events).

## Read-only mode for the entire scheduler

To make the entire scheduler read-only, set the [readonly](api/config/readonly.md) option to *true*.

~~~js
scheduler.config.readonly = true;
...
scheduler.init('scheduler_here',new Date(2019, 5,11),"month");
~~~
Note, when the entire scheduler is non-editable, users can't open the lightbox.


## Read-only mode for the entire lightbox

To leave for users the possibility to open the lightbox, but to forbid any editing inside it, set the [readonly_form](api/config/readonly_form.md) option to *true*:


~~~js
scheduler.config.readonly_form = true;
...
scheduler.init('scheduler_here',new Date(2019, 5,11),"month");
~~~

:::note
The [readonly](api/config/readonly.md) option is provided in the [readonly](guides/extensions-list.md#readonly) extension and to use it, enable the extension on the page.

## Read-only mode for a lightbox's section

To make a specific lightbox's section read-only, use the 'disabled' property of a DOM element of the related section object:

~~~js
scheduler.config.lightbox.sections="["
    {name:"description", height:200, map_to:"text", type:"textarea" , focus:true},
    {name:"time", height:72, type:"time", map_to:"auto"}
];

scheduler.attachEvent("onLightbox", function(){
   var section = scheduler.formSection("description");
   section.control.disabled = true;
});
~~~

:::note
Note, you refer to the section through its type and all sections that have this type will be read-only at once
:::

## Read-only mode for specific events

To make specific events read-only, add the property 'read-only' to them and set it to true:

~~~js
scheduler.getEvent(id).readonly = true;
~~~

:::note
The functionality is provided in the [readonly](guides/extensions-list.md#readonly) extension and to use it, enable the extension on the page.
