Creating Engaging Vue Apps with Quasar: Virtual Scrolling
Written on
Chapter 1: Introduction to Quasar
Quasar is a widely used UI framework for Vue, designed to help developers create visually appealing applications with ease.
In this guide, we will delve into the process of building Vue applications utilizing the Quasar UI library.
Section 1.1: Horizontal Virtual Scrolling
To implement a horizontal virtual scrolling feature, we can utilize the virtual-scroll-horizontal property. Here’s a sample of how this might look:
<q-virtual-scroll :items="items" virtual-scroll-horizontal>
<template v-slot="{ item }">
<div>{{ item }}</div></template>
</q-virtual-scroll>
The above example demonstrates a basic setup for horizontal virtual scrolling.

Section 1.2: Customizing Item Templates
We can personalize the item template to showcase elements according to our specific requirements. This is achieved by placing the item template within the default slot. Here’s how you can do that:
<q-virtual-scroll :items="items">
<template v-slot="{ item }">
<div class="custom-item">{{ item }}</div></template>
</q-virtual-scroll>
This customization allows for greater flexibility in displaying list items.
Subsection 1.2.1: Table Style Virtual Scrolling
We also have the option to present items in a table-style virtual scrolling container. This can be accomplished as follows:
<q-virtual-scroll :items="items" virtual-scroll-item-size="100">
<template v-slot="{ item }">
<q-tr>
<q-td>{{ item }}</q-td></q-tr>
</template>
</q-virtual-scroll>
In this configuration, we define the columns within the default slot.
To adjust the dimensions of the items, we utilize the virtual-scroll-item-size property to specify the height or width in pixels, depending on whether the scrolling is vertical or horizontal.
Additionally, the virtual-scroll-sticky-size-start and virtual-scroll-sticky-size-end properties can be employed to modify the dimensions of the sticky sections at both the start and end of the list.
Chapter 2: Conclusion
By leveraging Quasar's q-virtual-scroll component, developers can seamlessly incorporate a variety of virtual scrolling styles into their applications.
