+  InfiniteScrollSelect.vue
+
+  A reusable select component that supports:
+  - Infinite scrolling with paginated API
+  - Dynamic search filtering. Needs minimum
+  - Deduplicated option loading
+  - Auto-fetching of preselected value if not present in the initial result
+
+  Usage Example:
+
+  <infinite-scroll-select
+    v-model:value="form.account"
+    api="listAccounts"
+    :apiParams="accountsApiParams"
+    resourceType="account"
+    optionValueKey="name"
+    optionLabelKey="name"
+    @change-option-value="handleAccountNameChange" />
+
+  Props:
+  - api (String, required): API command name (e.g., 'listAccounts')
+  - apiParams (Object, optional): Additional parameters passed to the API
+  - resourceType (String, required): The key in the API response containing the resource array (e.g., 'account')
+  - optionValueKey (String, optional): Property to use as the value for options (e.g., 'name'). Default is 'id'
+  - optionLabelKey (String, optional): Property to use as the label for options (e.g., 'name'). Default is 'name'
+  - defaultOption (Object, optional): Preselected object to include initially
+  - showIcon (Boolean, optional): Whether to show icon for the options. Default is true
+  - defaultIcon (String, optional): Icon to be shown when there is no resource icon for the option. Default is 'cloud-outlined'
+
+  Events:
+  - @change-option-value (Function): Emits the selected option value(s) when value(s) changes. Do not use @change as it will give warnings and may not work
+  - @change-option (Function): Emits the selected option object when value changes. Works only when mode is not multiple
+
+  Features:
+  - Debounced remote filtering
+  - Custom dropdown footer/header (e.g., clear search button)
+  - Handles preselection and fetches missing option automatically
