+# Known issues
+
+## Unsupported input types
+
+Please use Maska only for inputs of the following types: `text`, `search`, `URL`, `tel` and `password`.
+If you need a numeric keyboard, use `type="text"` with attribute `inputmode="numeric"`:
+
+```html
+<input type="text" inputmode="numeric">
+```
+
+## Vuetify and other UI frameworks
+
+Some frameworks with custom components may not pass `data-` attributes to native input elements. In such cases, you will need to set the mask and other options using directive value:
+
+```vue
+<script setup>
+const options = { mask: '#-#' }
+</script>
+
+<input v-maska="options">
+```
