Flows

1. Render in modal on click

1. Click on element with data-mxqv-click.
2. JS reads mode, data_action, element, id, title.
3. For native/bootstrap the modal opens immediately (loading state), then POST is sent to connector.php (action=render, including modal_library).
4. For fancybox POST runs first, then Fancybox opens with the returned HTML.
5. On success HTML is inserted into the chosen mode container:
   • native → #mxqv-modal-body .qv-modal__content-area;
   • bootstrap → #mxqv-bootstrap-modal-body .qv-modal__content-area;
   • fancybox → current Fancybox slide.
6. After insert, mxqv:loaded is dispatched.

2. Render on mouseover

1. Hover over element with data-mxqv-mouseover.
2. Timer starts using mouseoverDelay from window.mxqvConfig.
3. If cursor is still there when timer ends, the same render request runs.
4. If cursor leaves earlier, timer is cancelled.

3. selector mode (no built-in modal)

1. Trigger has data-mxqv-mode="selector" and data-mxqv-output.
2. JS inserts loading indicator into the target container.
3. After response, replaces container content with html or error message.

4. Prev/next navigation in list

1. Trigger is inside container with data-mxqv-parent data-mxqv-loop="true".
2. JS builds list of triggers inside that container.
3. Buttons [data-mxqv-nav="prev|next"] change current index.
4. At list boundaries buttons are hidden.

5. Add to cart from quick view

1. Render uses MiniShop3 form (data-ms3-form, ms3_action=cart/add).
2. After HTML is inserted, ms3.productCardUI.reinit() is called (if available).
3. Add to cart works without page reload.

6. ms3Variants inside quick view

1. Processor for msProduct adds has_variants, variants_html and variants_json (when ms3Variants is installed).
2. In chunk, variants_json is put in data-mxqv-variants-json via :htmlent.
3. JS finds .qv-product[data-mxqv-variants] and only handles flag true|1|yes|on.
4. JS listens for click on [data-variant-id] and change on select/input in .qv-product__variants.
5. On variant change it updates price, old price and image.

7. Error flow

1. On validation error connector returns {success:false, message, html:''}.
2. In modal mode the message is shown in modal content.
3. In selector mode the message is inserted into the target container.
