+The DOM structure of this component doesn't change once rendered.
+Comparing to others using `v-if`, which generate sub-nodes while expanded.
+While working on long list of items, lags will be obvious.
 
-### Customize configuration
-See [Configuration Reference](https://cli.vuejs.org/config/).
+* This component will have a lag when once it is being rendered. After it is
+rendered, sub-trees are controlled by CSS, no DOM structure happens.
+* `v-if` components will lag whenever sub-trees are expanded, every time they
+are expanded.
