--- title: Markdown editor --- import AutoScreenshot from "@components/AutoScreenshot.astro" import UtilityInjection from "@components/UtilityInjection.astro" ## Introduction The markdown editor allows you to edit and preview markdown content, as well as upload images using drag and drop. ```php use Filament\Forms\Components\MarkdownEditor; MarkdownEditor::make('content') ``` ## Security By default, the editor outputs raw Markdown and HTML, and sends it to the backend. Attackers are able to intercept the value of the component and send a different raw HTML string to the backend. As such, it is important that when outputting the HTML from a Markdown editor, it is sanitized; otherwise your site may be exposed to Cross-Site Scripting (XSS) vulnerabilities. When Filament outputs raw HTML from the database in components such as `TextColumn` and `TextEntry`, it sanitizes it to remove any dangerous JavaScript. However, if you are outputting the HTML from a Markdown editor in your own Blade view, this is your responsibility. One option is to use Filament's `sanitizeHtml()` helper to do this, which is the same tool we use to sanitize HTML in the components mentioned above: ```blade {!! str($record->content)->markdown()->sanitizeHtml() !!} ``` ## Customizing the toolbar buttons You may set the toolbar buttons for the editor using the `toolbarButtons()` method. The options shown here are the defaults: ```php use Filament\Forms\Components\MarkdownEditor; MarkdownEditor::make('content') ->toolbarButtons([ ['bold', 'italic', 'strike', 'link'], ['heading'], ['blockquote', 'codeBlock', 'bulletList', 'orderedList'], ['table', 'attachFiles'], ['undo', 'redo'], ]) ``` Each nested array in the main array represents a group of buttons in the toolbar. As well as allowing a static value, the `toolbarButtons()` method also accepts a function to dynamically calculate it. You can inject various utilities into the function as parameters. ## Uploading images to the editor You may customize how images are uploaded using configuration methods: ```php use Filament\Forms\Components\MarkdownEditor; MarkdownEditor::make('content') ->fileAttachmentsDisk('s3') ->fileAttachmentsDirectory('attachments') ``` As well as allowing static values, the `fileAttachmentsDisk()` and `fileAttachmentsDirectory()` methods also accept functions to dynamically calculate them. You can inject various utilities into the function as parameters.
