使用方法(svg-icon为admin-element-vue的icon组件):

 <EIconPicker v-model="form.icon" :options="iconOptions">
               <template v-slot:prepend>
                 <svg-icon
                  :name="prefixIcon"
                  class="disabled"
                />
              </template>

               <template v-slot:icon="slotProps">
                  <svg-icon
                  :name="slotProps.icon"
                  class="disabled"
                />
              </template>

          </EIconPicker>
