It is used to remove a row while table structure does not effect. The difference is just the jQuery part, where I will use the:Īs such, the collapse value also used for table elements. I will use the same example as above, but this time using the CSS visibility property to show and hide the menu. This will make the menu visible again and links will move down.
#How to show hidden text in html code
If you click the show menu link after that, the jQuery query code will add the display: initial value. As menu disappears, the links will move up, occupying the space of the menu because CSS display property does not occupy the element space after display: none is used. By using display: none, the div will be hidden and so the whole menu as well. As you click on the hide menu link, the jQuery code will be used on the click event of that link to add: display: none property to the parent div.Īs such, the parent div contains the menu, which is the combination of ul, li and elements. Two links are given after the menu: hide menu / show menu.
The links act as the menu items.Īpart from other CSS properties, that are many to design this menu, the display property is not used initially, that means the menu will be visible. In this demo, I have used a div element that contains unordered list, list items and hyperlinks. It will behave like a block element if the block value is used in display property.Ī display example to show / hide menu – div, li, and links For example, the span is an inline element. Let's create a CSS class invisible having the visibility: hidden style.Using the block value makes the opposite. When the object literal is assigned to the :class, Vue would apply the "className" as a class to the element if boolValue is true. Unfortunately, you cannot use v-show directive because it applies only display: none style.īut a viable solution is to use :class binding, which is pretty flexible in Vue.
What if you need to hide the element's content while keeping the space it occupies? The CSS style that hides the element content but keeps its space is visibility: hidden. Thus toggling the element's visibility using v-show is relatively cheap (compared to v-if described above), so you might use this directive with an element which visibility is toggled often. V-show, when assigned with false, applies display: none inline style and hides the element visually and makes almost no modifications to the DOM.
However, the second is hidden because Vue applies display: none inline style, thanks to v-show="false".ĭisplay: none applied to an element makes the element disappear completely.Ĭhallenge: how can you implement in Vue a button that toggles the display of an element? Share your solution in a comment! 2.1 When to use v-show The first element is visible on the screen. V-show is a built-in directive that shows or hides the element visually:
Often it's useful to keep the element present in the DOM, but have it visually hidden using CSS styles. For example, to show/hide a section having detailed information about an entity.Ĭhallenge: would v-if render the element if assigned with 0? What about '0'? 2. You'd use v-if on the elements which visibility isn't toggled too often and is initially hidden. But it has a low initialization cost if the element is initially hidden. V-if toggling is relatively expensive (since each time you change v-if value the element is inserted/removed from DOM, as well event listeners are initialized/uninitialized) compared to v-show (presented in the next section). When v-if directive is assigned with false, Vue also doesn't initialize the event listeners on the element, even if you explicitly use the event directives. In simple words, v-if directive allows you to show or hide the element just by inserting or not the element into the DOM. The second element, however, isn't rendered into theĭOM because v-if="value2" was supplied with a false. The first element is rendered because v-if="value1" was supplied with a true value.
