Setting up line-height via TinyMCE - css

Question

Is there a way to give user possibility to easily changing line-height attribute of paragraph in tinyMCE editor? Something like its native "Font size" or "Format" <select> or anything else. I know I can use "edit CSS" functionality and set it up there. I'm looking for something more user-friendly.
I can't find it anywhere.

Answer 1

I found this PlugIn for TinyMCE version 4.1.5 (2014-09-09)
https://github.com/castler/tinymce-line-height-plugin
Setting up like this:
tinymce.init({
plugins: 'lineheight',
toolbar: 'lineheightselect'
});
Also you could configure the different heights like that:
tinymce.init({
lineheight_formats: "8pt 9pt 10pt 11pt 12pt 14pt 16pt 18pt 20pt 22pt 24pt 26pt 36pt",
});
I tested this and it works great.

I have found a good way for adding custom line-height to tinymce but this is a trick.
I am using tinymce v5 and with these codes i can use line height with a nice select option.
you have to add these lines to init codes of tiny mce:
tinymce.init({
selector: 'textarea',
height: 500,
plugins: 'table wordcount',
toolbar: ' styleselect ',
content_css: [
'//fonts.googleapis.com/css?family=Lato:300,300i,400,400i',
'//www.tiny.cloud/css/codepen.min.css'
],
toolbar: 'styleselect'
content_style: '.lineheight20px { line-height: 20px; }' +
'.lineheight22px { line-height: 22px; }' +
'.lineheight24px { line-height: 24px; }' +
'.lineheight26px { line-height: 26px; }' +
'.lineheight28px { line-height: 28px; }' +
'.lineheight30px { line-height: 30px; }' +
'.lineheight32px { line-height: 32px; }' +
'.lineheight34px { line-height: 34px; }' +
'.lineheight36px { line-height: 36px; }' +
'.lineheight38px { line-height: 38px; }' +
'.lineheight40px { line-height: 40px; }' +
'.tablerow1 { background-color: #D3D3D3; }',
formats: {
lineheight20px: { selector: 'span,p,h1,h2,h3,h4,h5,h6,td,th,div,ul,ol,li,table,img', classes: 'lineheight20px' },
lineheight22px: { selector: 'span,p,h1,h2,h3,h4,h5,h6,td,th,div,ul,ol,li,table,img', classes: 'lineheight22px' },
lineheight24px: { selector: 'span,p,h1,h2,h3,h4,h5,h6,td,th,div,ul,ol,li,table,img', classes: 'lineheight24px' },
lineheight26px: { selector: 'span,p,h1,h2,h3,h4,h5,h6,td,th,div,ul,ol,li,table,img', classes: 'lineheight26px' },
lineheight28px: { selector: 'span,p,h1,h2,h3,h4,h5,h6,td,th,div,ul,ol,li,table,img', classes: 'lineheight20px' },
lineheight30px: { selector: 'span,p,h1,h2,h3,h4,h5,h6,td,th,div,ul,ol,li,table,img', classes: 'lineheight30px' },
lineheight32px: { selector: 'span,p,h1,h2,h3,h4,h5,h6,td,th,div,ul,ol,li,table,img', classes: 'lineheight32px' },
lineheight34px: { selector: 'span,p,h1,h2,h3,h4,h5,h6,td,th,div,ul,ol,li,table,img', classes: 'lineheight34px' },
lineheight36px: { selector: 'span,p,h1,h2,h3,h4,h5,h6,td,th,div,ul,ol,li,table,img', classes: 'lineheight36px' },
lineheight38px: { selector: 'span,p,h1,h2,h3,h4,h5,h6,td,th,div,ul,ol,li,table,img', classes: 'lineheight38px' },
lineheight40px: { selector: 'span,p,h1,h2,h3,h4,h5,h6,td,th,div,ul,ol,li,table,img', classes: 'lineheight40px' }
},
style_formats: [
{ title: 'lineheight20px',format: 'lineheight20px' },
{ title: 'lineheight22px', format: 'lineheight22px' },
{ title: 'lineheight24px', format: 'lineheight24px' },
{ title: 'lineheight26px', format: 'lineheight26px' },
{ title: 'lineheight28px', format: 'lineheight28px' },
{ title: 'lineheight30px', format: 'lineheight30px' },
{ title: 'lineheight32px', format: 'lineheight32px' },
{ title: 'lineheight34px', format: 'lineheight34px' },
{ title: 'lineheight36px', format: 'lineheight36px' },
{ title: 'lineheight38px', format: 'lineheight38px' },
{ title: 'lineheight40px', format: 'lineheight40px' }
]
});
and at the end i have to say you need to find a "paragraph" word in the file of tinymce/themes/silver/theme.min.js and change it to "line-height" if you want to see the line-height name instead of paragraph name.
this word is in line of 290855 of that file.
and this job is called custom format in tinymce that if you want to find it check this link:
https://www.tiny.cloud/docs/demo/format-custom/
and I have to say you need to add this css codes to your css file:
.lineheight22px{
line-height: 22px;
}
.lineheight24px{
line-height: 24px;
}
.lineheight26px{
line-height: 26px;
}
.lineheight28px{
line-height: 28px;
}
.lineheight30px{
line-height: 30px;
}
.lineheight32px{
line-height: 32px;
}
.lineheight34px{
line-height: 34px;
}
.lineheight36px{
line-height: 36px;
}
.lineheight38px{
line-height: 38px;
}
.lineheight40px{
line-height: 40px;
}

Indeed, TinyMCE doesn't have line-height control as it has for font names or font sizes, but you can easily add it with the style_formats. I used this config:
// custom formatting is under Format > formats, so make sure it's in your menu (it is, by default)
const editorOptions = {
// Notice that it overrides Format > formats
style_formats: [
{
title: 'Line height',
items: [
{
title: 'Default',
inline: 'span',
// `inline-block` because CSS `line-height` doesn't affect multiline `span`
styles: { 'line-height': 'normal', display: 'inline-block' }
},
{
title: '40px',
inline: 'span',
styles: { 'line-height': '40px', display: 'inline-block' }
},
// add as more as you need
]
},
// ...
]
}
