#### Toolbar icons
Below are the built-in toolbar icons (only some of which are enabled by default), which can be reorganized however you like. "Name" is the name of the icon, referenced in the JS. "Action" is either a function or a URL to open. "Class" is the class given to the icon. "Tooltip" is the small tooltip that appears via the title="" attribute. Note that shortcut hints are added automatically and reflect the specified action if it has a keybind assigned to it (i.e. with the value of action set to bold and that of tooltip set to Bold, the final text the user will see would be "Bold (Ctrl-B)").
Additionally, you can add a separator between any icons by adding "|" to the toolbar array.
Name | Action | Tooltip
Class
:--- | :----- | :--------------
bold | toggleBold | Bold
fa fa-bold
italic | toggleItalic | Italic
fa fa-italic
strikethrough | toggleStrikethrough | Strikethrough
fa fa-strikethrough
heading | toggleHeadingSmaller | Heading
fa fa-header
heading-smaller | toggleHeadingSmaller | Smaller Heading
fa fa-header
heading-bigger | toggleHeadingBigger | Bigger Heading
fa fa-lg fa-header
heading-1 | toggleHeading1 | Big Heading
fa fa-header fa-header-x fa-header-1
heading-2 | toggleHeading2 | Medium Heading
fa fa-header fa-header-x fa-header-2
heading-3 | toggleHeading3 | Small Heading
fa fa-header fa-header-x fa-header-3
code | toggleCodeBlock | Code
fa fa-code
quote | toggleBlockquote | Quote
fa fa-quote-left
unordered-list | toggleUnorderedList | Generic List
fa fa-list-ul
ordered-list | toggleOrderedList | Numbered List
fa fa-list-ol
clean-block | cleanBlock | Clean block
fa fa-eraser fa-clean-block
link | drawLink | Create Link
fa fa-link
image | drawImage | Insert Image
fa fa-picture-o
table | drawTable | Insert Table
fa fa-table
horizontal-rule | drawHorizontalRule | Insert Horizontal Line
fa fa-minus
preview | togglePreview | Toggle Preview
fa fa-eye no-disable
side-by-side | toggleSideBySide | Toggle Side by Side
fa fa-columns no-disable no-mobile
fullscreen | toggleFullScreen | Toggle Fullscreen
fa fa-arrows-alt no-disable no-mobile
guide | This link | Markdown Guide
fa fa-question-circle
Customize the toolbar using the toolbar option like:
`JavaScript
// Customize only the order of existing buttons
var simplemde = new SimpleMDE({
toolbar: ["bold", "italic", "heading", "|", "quote"],
});
// Customize all information and/or add your own icons
var simplemde = new SimpleMDE({
toolbar: [{
name: "bold",
action: SimpleMDE.toggleBold,
className: "fa fa-bold",
title: "Bold",
},
{
name: "custom",
action: customFunction(editor){
// Add your own code
},
className: "fa fa-star",
title: "Custom Button",
},
"|", // Separator
...
],
});
`
#### Keyboard shortcuts
SimpleMDE comes with an array of predefined keyboard shortcuts, but they can be altered with a configuration option. The list of default ones is as follows:
Shortcut | Action
:------- | :-----
Cmd-' | "toggleBlockquote"
Cmd-B | "toggleBold"
Cmd-E | "cleanBlock"
Cmd-H | "toggleHeadingSmaller"
Cmd-I | "toggleItalic"
Cmd-K | "drawLink"
Cmd-L | "toggleUnorderedList"
Cmd-P | "togglePreview"
Cmd-Alt-C | "toggleCodeBlock"
Cmd-Alt-I | "drawImage"
Cmd-Alt-L | "toggleOrderedList"
Shift-Cmd-H | "toggleHeadingBigger"
F9 | "toggleSideBySide"
F11 | "toggleFullScreen"
Here is how you can change a few, while leaving others untouched:
`JavaScript`
var simplemde = new SimpleMDE({
shortcuts: {
"toggleOrderedList": "Ctrl-Alt-K", // alter the shortcut for toggleOrderedList
"toggleCodeBlock": null, // unbind Ctrl-Alt-C
"drawTable": "Cmd-Alt-T" // bind Cmd-Alt-T to drawTable action, which doesn't come with a default shortcut
}
});
Shortcuts are automatically converted between platforms. If you define a shortcut as "Cmd-B", on PC that shortcut will be changed to "Ctrl-B". Conversely, a shortcut defined as "Ctrl-B" will become "Cmd-B" for Mac users.
The list of actions that can be bound is the same as the list of built-in actions available for toolbar buttons.
#### Height
To change the minimum height (before it starts auto-growing):
`CSS`
.CodeMirror, .CodeMirror-scroll {
min-height: 200px;
}
Or, you can keep the height static:
`CSS`
.CodeMirror {
height: 300px;
}
`JavaScript`
var simplemde = new SimpleMDE();
simplemde.codemirror.on("change", function(){
console.log(simplemde.value());
});
method. Note that this clears up the autosave (if enabled) associated with it. The textarea will retain any text from the destroyed SimpleMDE instance.`JavaScript
var simplemde = new SimpleMDE();
...
simplemde.toTextArea();
simplemde = null;
`Useful methods
The following self-explanatory methods may be of use while developing with SimpleMDE.`js
var simplemde = new SimpleMDE();
simplemde.isPreviewActive(); // returns boolean
simplemde.isSideBySideActive(); // returns boolean
simplemde.isFullscreenActive(); // returns boolean
simplemde.clearAutosavedValue(); // no returned value
``CodeMirror is the backbone of the project and parses much of the Markdown syntax as it's being written. This allows us to add styles to the Markdown that's being written. Additionally, a toolbar and status bar have been added to the top and bottom, respectively. Previews are rendered by Marked using GFM.
