MONA Fields is a plugin that lets you create and manage custom content fields for each page, post or product on your website, developed in-house by MONA to replace Advanced Custom Fields (ACF). Put simply, it's the tool that lets your website display rich content exactly as designed, instead of just the default editor box.
And here's the reassuring part: MONA Fields comes with a lifetime license per domain, so there's no yearly purchase and no activation key to re-enter every time it expires, as with commercial plugins.
What custom content fields are, and why a website needs them
A service page usually isn't just one block of text. It has its own heading, illustrations, a list of benefits, a specs table and an FAQ block. Each of these is a “content field”. With a content field management tool, your editors just fill in each ready-made box, and the website displays it nicely in the right layout, without touching code.
Many good-looking websites in Vietnam rely on ACF for this. MONA Fields does exactly that job, but it's genuine MONA software and doesn't tie you to foreign license fees.
Dynamic content management for pages, posts and products
With MONA Fields, you attach content fields to any content type: an about page, a news post or a product page. Editors open it and see exactly the boxes they need to fill in, such as an image box, a description box or a category picker. That keeps content consistent: whoever in the company updates it, it comes out in the right format, with no worry about everyone doing it their own way.

Editor for repeaters, flexible content and field groups
Real content rarely has a fixed quantity. Today a service has three highlights, tomorrow you want to add a fourth. MONA Fields supports three advanced content-building types to handle this.
- Repeater: a content template repeated as many times as you like, such as a list of branches or a list of FAQs. To add an item, just click to add a row.
- Flexible content: you build a page from many different block types and arrange them in any order, like stacking content bricks to form a complete page.
- Field group: groups related boxes into one cluster to keep things tidy, so editors understand each part at a glance.
Replace ACF without breaking your website
This is the technically hard part, and where MONA has invested a lot of effort. On websites built with ACF, the theme calls content field data in many places. Remove ACF crudely and the website may go blank.
MONA Fields reads the same data store ACF saved, so after the switch the website displays exactly as before, with no content lost. You get rid of the third-party licensing obligation, keep the website that's already running well, and from then on edit content with MONA software.
FAQ
If I'm using ACF, will I lose content when switching to MONA Fields?
No. MONA Fields reads the same saved data, so the website displays intact and you don't have to re-enter any content.
Can someone without technical skills update content themselves?
Yes. Editors just fill in the ready-made boxes, and the plugin takes care of displaying it nicely in the right layout.
Do I have to enter an activation key every year?
No. It's a lifetime license per domain, granted once and used forever.
