BUG: RTE misplaced when opened right after dropping `activeOnRender` component

[mcottret]

Version: 0.17.4

Are you able to reproduce the bug from the demo?

• [x] Yes
• [ ] No

Steps to reproduce:

• Go to the demo
• Drop a "Text" block inside the canvas
• Click on the "Text" component that was just dropped
• The opened RTE is misplaced (cf attached screenshot)

What is the expected behavior?

The opened RTE should be positioned correctly

What is the current behavior?

The RTE is misplaced, it hides the "Text" component's content & can prevent editing properly (especially when using bigger custom RTE like CKEditor).

This only happens when the RTE is first opened & only if the dropped block is a "Text" component with activeOnRender option set to true.

This is caused by a miscalculation of the toolbar's position when its offsetHeight equals 0. Itself due to its parent (CanvasView.toolsEl) being set to display: none at this time (because rte.enable is called on drop when activeOnRender is true, which happens while the component is unselected as opposed to normal, hence its toolsEl still being set to display: none)

Proposed solution:

Selecting the component before triggering activeOnRender's active event seems to fix the issue.

Concretely, adding em.setSelected(result); before result.trigger('active'); here should do it, unless I'm missing something.

I could take care of the PR if this looks good to you :)

Are you able to attach screenshots, screencasts or a live demo?

Yes, I guess you're right. It doesn't actually make sense activating RTE without selecting the component (it probably makes sense with all other "activatable" blocks).

Hello, just updated the file from commit bb4a661, and i think it's so close, i'm using the grapesjs-ckeditor code and the first open of RTE, i'ts placed right:

But at the second time the rte is open, it's misplaced again... :/

I'll keep checking for it :/

The code i'm get from grapesjs-ckeditor

```javascript let c = { options:{ sharedSpaces:'' } }; let defaults = { // CKEditor options options: {}, // On which side of the element to position the toolbar // Available options: 'left|center|right' position: 'left', }; // Load defaults for (let name in defaults) { if (!(name in c)) c[name] = defaults[name]; } if (!CKEDITOR) { throw new Error('CKEDITOR instance not found'); } editor.setCustomRte({ enable(el, rte) { // If already exists I'll just focus on it if(rte && rte.status != 'destroyed') { this.focus(el, rte); return rte; } el.contentEditable = true; // Seems like 'sharedspace' plugin doesn't work exactly as expected // so will help hiding other toolbars already created let rteToolbar = editor.RichTextEditor.getToolbarEl(); [].forEach.call(rteToolbar.children, (child) => { child.style.display = 'none'; }); // Check for the mandatory options var opt = c.options; var plgName = 'sharedspace'; if (opt.extraPlugins) { if (typeof opt.extraPlugins === 'string') opt.extraPlugins += ',' + plgName; else opt.extraPlugins.push(plgName); } else { opt.extraPlugins = plgName; } if(!c.options.sharedSpaces) { c.options.sharedSpaces = {top: rteToolbar}; } // Init CkEditors rte = CKEDITOR.inline(el, c.options); /** * Implement the `rte.getContent` method so that GrapesJS is able to retrieve CKE's generated content (`rte.getData`) properly * * See: * - {@link https://github.com/artf/grapesjs/issues/2916} * - {@link https://github.com/artf/grapesjs/blob/dev/src/dom_components/view/ComponentTextView.js#L80} * - {@link https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_editor.html#method-getData} */ rte.getContent = rte.getData; // Make click event propogate rte.on('contentDom', () => { var editable = rte.editable(); editable.attachListener(editable, 'click', () => { el.click(); }); }); // The toolbar is not immediatly loaded so will be wrong positioned. // With this trick we trigger an event which updates the toolbar position rte.on('instanceReady', e => { var toolbar = rteToolbar.querySelector('#cke_' + rte.name); if (toolbar) { toolbar.style.display = 'block'; } editor.trigger('canvasScroll') }); // Prevent blur when some of CKEditor's element is clicked rte.on('dialogShow', e => { const editorEls = grapesjs.$('.cke_dialog_background_cover, .cke_dialog'); ['off', 'on'].forEach(m => editorEls[m]('mousedown', stopPropagation)); }); this.focus(el, rte); return rte; }, disable(el, rte) { el.contentEditable = false; if(rte && rte.focusManager) rte.focusManager.blur(true); }, focus(el, rte) { // Do nothing if already focused if (rte && rte.focusManager.hasFocus) { return; } el.contentEditable = true; rte && rte.focus(); }, }); // Update RTE toolbar position editor.on('rteToolbarPosUpdate', (pos) => { // Update by position switch (c.position) { case 'center': let diff = (pos.elementWidth / 2) - (pos.targetWidth / 2); pos.left = pos.elementLeft + diff; break; case 'right': let width = pos.targetWidth; pos.left = pos.elementLeft + pos.elementWidth - width; break; } if (pos.top <= pos.canvasTop) { pos.top = pos.elementTop + pos.elementHeight; } // Check if not outside of the canvas if (pos.left < pos.canvasLeft) { pos.left = pos.canvasLeft; } }); ```

I have the same issue. Did anyone find a solution?

Hi. Me and @ronaldohoch have found a workaround for this problem.

We trigger the scroll event when the RTE is enabled. Here's the code:

    // Trigger scroll event from canvas so that grapesjs
    // fix CKEditor position correctly
    editor.on("rte:enable", () => {
        editor.trigger('canvasScroll');
    });

Thank you for your answer, i tried your code after const editor = grapesjs.init({...}) But it didn't change anything, i thought it's about my grapesjs version and, i upgraded my version but still missplaced when i open the text block for the first time

Can you provide some code in jsfiddle? https://jsfiddle.net/szLp8h4n
