 ## SCSS Variables
 
 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`](https://github.com/sagalbot/vue-select/blob/master/src/scss/global/_variables.scss).

+## Option Wrapping Strategy
+
+When options in the dropdown are wider than the dropdown itself, there are three strategies
+available. The strategy can be set with the `dropdownOptionWrap` prop. This prop accepts one of
+three strings:
+
+### `wrap`
+
+Break options that are wider than the dropdown onto the next line. No horizontal scrollbar.
+
+```vue
+<v-select dropdown-option-wrap="wrap" />
+```
+
+<OptionWrapStrategy wrap="wrap" />
+
+### `truncate`
+
+Truncate options that are wider than the dropdown using an ellipsis `...`. No horizontal scrollbar.
+
+```vue
+<v-select dropdown-option-wrap="truncate" />
+```
+
+<OptionWrapStrategy wrap="truncate" />
+
+### `nowrap`
+
+Don't wrap or truncate options wider than the dropdown. Introduces horizontal scrollbar.
+
+```vue
+<v-select dropdown-option-wrap="nowrap" />
+```
+
+<OptionWrapStrategy wrap="nowrap" />
