Step 1 — Element widgets, again

Remember the ? We can use elements from when creating applications with UI. It is enough to add the desired element to the HTML file.

Don't forget to initialize state so the buttons work properly

Example:

<div>
	<div>
		<el-button type="success">Success</el-button>
        	<el-button type="warning">Warning</el-button>
        	<el-button type="danger">Danger</el-button>
        	<el-button type="info">Info</el-button>
	</div>
	<hr/>
	<div>
		state.checkedList value: {{state.checkedList}}
	</div>
	<hr/>
	<div>

		<el-checkbox-group v-model="state.checkedList">
		    <el-checkbox label="Option A"></el-checkbox>
		    <el-checkbox label="Option B"></el-checkbox>
		    <el-checkbox label="Option C"></el-checkbox>
		</el-checkbox-group>
	</div>
</div>

Result:


Step 2 — HTML Styles

Also you can create your own styles and apply them to elements. Inline styles are also available.

Example:

<div id="styling-your-app">
    <sly-style>
        #styling-your-app .our-custom-class {
        font-size: 50px;
        }
	</sly-style>

	<div class="our-custom-class">
		Text with custom class
	</div>
	<hr/>
	<div style="font-size: 24px">
		Text with custom style
	</div>
	<hr/>
	<div>
		Text without custom class
	</div>
</div>

Result:

Step 3 — Elements properties (Disabling, Hiding, Loading, Iterating)

Some elements of the HTML file have properties. They can be changed.

<div>
	<hr/>  <!-- disabling property -->
	<el-button type="success" :disabled="true">i'm disabled</el-button>

	<hr/> <!-- hiding(v-if) property -->
	<el-button type="success" v-if="false">i'm hidden</el-button>
	<el-button type="success" v-if="true">i'm not hidden</el-button>

	<hr/> <!-- loading property -->
	<el-button type="success" :loading="true">i'm loading</el-button>

	<hr/> <!-- iterating property -->
	<!--
	fill the data field:
	{"simpleData":
		{
			"now": "we",
			"can": "iterate",
			"in": "HTML!"
		}
	}
	-->

	<div v-for="v,k in data.simpleData" style="word-break: break-all;">
    		<b>{{k}}</b>: <span>{{v}}</span>
	</div>
</div>

Result:


You can use state to pass values to these properties!
