Vue Select offers many APIs for customizing the look and feel from the component. You can use scoped slots, custom child components, or modify the built in CSS properties.

CSS Variables

Vue Select uses custom CSS properties throughout the component to handle visual opinions. This allows for quite a bit of flexibility in styling, without having to hook into a build system for generating your own styles with something like SASS. If there is a value that you think should use a CSS property instead of a hardcoded CSS value, please submit a PR.

Dark Mode Example

Without writing any CSS yourself, you can completely customize the look and feel of Vue Select through the use of CSS variables. In this example, we adjust the colors of the component to match for a dark mode application.

In this case, the variables are scoped to only this implementation of the component, but you could place these variables anywhere in your applications CSS file to implement at a global level for your app.

Check the MDN docs for more info about CSS Custom Properties.

SCSS Deprecated in v3.18

::: warning Deprecation Notice The SCSS build been deprecated for the v3.x release, and will be removed in v4.0.0. The files will remain in the v3 codebase if you really need them, but the recommended approach is to leverage the included CSS variables instead. :::

Variables are leveraged in as much of the component styles as possible. If you really want to dig into the SCSS, the files are located in src/scss. The variables listed below can be found at src/scss/global/_variables .

All variables are implemented with !default in order to make them easier to override in your application.

Overriding Default Styles

Vue Select takes the approach of using selectors with a single level of specificity, while using classes that are very specific to Vue Select to avoid collisions with your app.

Most classes within Vue Select use the vs__ prefix, and selectors are generally a single classname – unless there is a state being applied to the component.

In order to override a default property in your app, you should add one level of specificity. The easiest way to do this, is to add .v-select before the vs__* selector if you want to adjust all instances of Vue Select, or add your own classname if you just want to affect one.

Dropdown Transition

By default, the dropdown transitions with a .15s cubic-bezier opacity fade in/out. The component uses the VueJS transition system. By default, the transition name is vs__fade. There's a couple ways to override or change this transition.

1. Use the transition prop. Applying this prop will change the name of the animation classes and negate the default CSS. If you want to remove it entirely, you can set it to an empty string.

<v-select transition="" />

2. You can also override the default CSS for the vs__fade transition. Again, if you wanted to eliminate the transition entirely:

.vs__fade-enter-active,
.vs__fade-leave-active {
    transition: none;
}
