Ui/Ux. Field widths and matrix tabs.
Use flexbox/grid for field widths on dekstop/tablets view. On mobile view, just add a media query, full width and call it the day.

Set width for field :

Groups, tabs and horizontal fields with defined column sizes would indeed be a great addition!
@H-i-red feature requests for all of this already exist. See https://github.com/craftcms/cms/issues/2409 and https://github.com/craftcms/cms/issues/1138
oh crap sorry..
The horizontal fields with widths is a new feature request though I think
@H-i-red is that photoshop or do u have tabs within matrix fields? 🤔
@davidhellmann I do have tabs ; ) !
I did a hacky solution by creating a module to add css and js to admin. Then I took the plugin "entry instructions" targeted the fields with js and css... But hey it works.. lol...
Here are the js if interested : You have to add a observer to check for dom changes (New matrix blocks..) I don´t have the plugin skills atm. but someone else maybe does.. 🤔
jQuery(document).ready(function ($) {
'use strict';
var config = { childList: true };
$(".matrix .blocks").each(function () {
var target = this;
var observer = new MutationObserver(function(mutations) {
mutations.every(function(mutation) {
if (mutation.addedNodes.length > 0) {
tabber($(mutation.addedNodes));
}
});
});
observer.observe(target, config);
});
function tabber(obj) {
if (obj) {
var tabs = obj.find('div.field[data-type$="EntryInstructionsField"]');
tabs.first().addClass("active");
tabs.on('click', function() {
tabs.removeClass("active");
$(this).addClass("active");
console.log("cool")
});
} else {
$('.matrixblock').each(function() {
var tabs = $(this).find('div.field[data-type$="EntryInstructionsField"]');
tabs.first().addClass("active");
tabs.on('click', function() {
tabs.removeClass("active");
$(this).addClass("active");
console.log("cool")
});
});
}
}
tabber();
});
Some of the css to hide/show the "inactive fields"..
.matrixblock div.field[data-type$="EntryInstructionsField"] ~ div {
display: none;
}
.matrixblock div.field[data-type$="EntryInstructionsField"].active ~ div {
display: block;
}
.matrixblock div.field[data-type$="EntryInstructionsField"].active ~ div.field[data-type$="EntryInstructionsField"] ~ div {
display: none;
}
OK, that sounds hacky :D but cool! :D haha
As of the next Craft 3.5 release, it will be possible to customize fields’ widths, setting them to either 25%, 50%, 75%, or 100% width.

Note that this doesn’t affect Matrix sub-fields yet, and will keep #2409 open to address the Matrix block tabs request.
Matrix sub-fields have now been updated to support custom field widths as well (see https://github.com/craftcms/cms/issues/6346#issuecomment-658919451).
