+
+### Model Modifiers
+
+#### .trim
+
+The `.trim` modifier trims the input value.
+
+```vue [page]
+<script lang="ts" setup>
+const modal = ref<string>("");
+</script>
+
+<template>
+  <RayTextarea v-model.trim="modal" />
+</template>
+```
+
+#### .number
+
+The `.number` modifier converts the input value to a number. Non-numeric values are ignored.
+
+```vue [page]
+<script lang="ts" setup>
+const modal = ref<number>(0);
+</script>
+
+<template>
+  <RayTextarea v-model.number="modal" />
+</template>
+```
+
+#### .lazy
+
+The `.lazy` modifier syncs the input value with the model only on `change` event.
+
+```vue [page]
+<script lang="ts" setup>
+const modal = ref<string>("");
+</script>
+
+<template>
+  <RayTextarea v-model.lazy="modal" />
+</template>
+```
