Auto Expanding Menu on Hover

Today someone on the Slack asked a question about having the side navigation menu auto-expand when hovering it. So I thought I would share this with others as well.

It can be easily be done using only a couple of JavaScript lines of code:
(function(ut, $) {

var TREE_NAV_WIDGET_KEY = 'nav';

$(window).on('theme42ready', function() {
    /* Make sure that the navigation menu is collapsed on page load */
    if (ut.toggleWidgets.isExpanded(TREE_NAV_WIDGET_KEY)){

    /* Expand on mouse over, collapse on mouse out */
    $('.apex-side-nav.js-navCollapsed .t-Body-nav').hover(
        function() {

})(apex.theme42, apex.jQuery);
First thing we need to do is make sure that the side navigation is collapsed.
Then we add a hovering handler using the jQuery .hover() on the navigation menu container.

You'll end up with something like this:

Now triggers the custom navigation menu event.
Also calls the delayResize function so that any sticky headers get resized correctly when the side navigation menu is expanded and collapsed.

Edit 09-28
Rewrote to use namespacing, wrapped using the "theme42ready" event and replaced the collapsed/expand calls with the universal theme functions.

APEX Items the Application Builder Style

The APEX application builder has the items look and feel different compared to what you get in a regular application.

You might think that they are looking good and that you would like to display them the same way in your application.

Here's the CSS you can use to do just that:
/* Removes borders from items */
.t-Form-inputContainer input[type="text"],
.t-Form-inputContainer input.text_field,
.t-Form-inputContainer input.password,
.t-Form-inputContainer input.datepicker,
.t-Form-inputContainer span.display_only,
.t-Form-inputContainer input.popup_lov,
.t-Form-inputContainer select,
.t-Form-inputContainer select.selectlist[size="1"],
.t-Form-inputContainer select.yes_no,
.u-TF-item--select {
   background-color: transparent;
   border-top-color: transparent;
   border-left-color: transparent;
   border-right-color: transparent;

/* Removes decoration of the popup lov button */
.a-Button.a-Button--popupLOV {
    background-color: transparent;
    box-shadow: none;
.a-Button.a-Button--popupLOV:hover {
    background-color: #f8f8f8;
    box-shadow: 0 0 0 1px rgba(0, 0, 0, 0.125) inset;

/* Removes borders when displaying inline error  */
.t-Form-inputContainer input[type="text"].apex-page-item-error,
.t-Form-inputContainer input.text_field.apex-page-item-error,
.t-Form-inputContainer input.password.apex-page-item-error,
.t-Form-inputContainer input.datepicker.apex-page-item-error,
.t-Form-inputContainer span.display_only.apex-page-item-error,
.t-Form-inputContainer input.popup_lov.apex-page-item-error,
.t-Form-inputContainer select.apex-page-item-error,
   border-top-color: transparent;
   border-left-color: transparent;
   border-right-color: transparent;

/* Removes borders when displaying inline error (required with valid state) */
.t-Form-inputContainer input[type="text"].apex-page-item-error:required:valid,
.t-Form-inputContainer input.text_field.apex-page-item-error:required:valid,
.t-Form-inputContainer input.password.apex-page-item-error:required:valid,
.t-Form-inputContainer input.datepicker.apex-page-item-error:required:valid,
.t-Form-inputContainer span.display_only.apex-page-item-error:required:valid,
.t-Form-inputContainer input.popup_lov.apex-page-item-error:required:valid,
.t-Form-inputContainer select.apex-page-item-error:required:valid,
.u-TF-item--select.apex-page-item-error:required:valid {
    border-top-color: transparent;
    border-right-color: transparent;
    border-left-color: transparent;

/* Fix the select list error border color */
.t-Form-inputContainer select.apex-page-item-error{
    border-color: #eb6562;

Basically, the CSS will hide the top, left and right border of the items, while keeping the bottom border as well as the border's defined color. When the item is focused, all borders will be displayed as usual.

You'll end up with something like this:
