The TinyMCE4 Formula Editor is a powerful plugin that extends the capabilities of the TinyMCE4 rich text editor by adding comprehensive mathematical formula editing functionality. Unlike the base TinyMCE4 installation which lacks native math support, this plugin provides an intuitive interface for creating complex mathematical expressions directly within your editor.
Key Features of the TinyMCE4 Formula Editor
This robust formula editor offers numerous advantages for technical content creators, educators, and developers:
- Comprehensive Formula Support – Create fractions, scripts, radicals, integrals, operators, brackets, and mathematical functions with ease
- Special Character Library – Access Greek letters, mathematical operators, arrows, relation symbols, and script characters
- Complex Equation Handling – Build multi-line equations and nested expressions without limitations
- MathType-like Interface – Enjoy familiar point-and-click formula creation similar to commercial alternatives
- Client-Side Processing – All rendering occurs in the browser with no server-side dependencies
- Image Export – Save formulas as images for compatibility across all platforms
Detailed Installation Guide
Implementing the TinyMCE4 Formula Editor requires just a few simple steps:
Step 1: File Placement
Upload the plugin files to your TinyMCE plugins directory, typically located at:
/js/tinymce/plugins/
Step 2: Configuration Update
Modify your TinyMCE initialization script to include the formula editor:
tinymce.init({ selector: "textarea", plugins: [ "leaui_formula", "advlist autolink link lists charmap hr anchor pagebreak", "directionality textcolor paste fullpage textcolor" ], paste_data_images: true, toolbar1: "leaui_formula | styleselect formatselect fontselect fontsizeselect | bold italic underline strikethrough" });
