Examples

Here is an example of how to create a study legend on the chart. We use the cq-marker attribute to ensure that it floats inside the chart. We set the optional cq-panel-only attribute so that only studies from this panel are displayed. 

<cq-study-legend cq-marker-label="Studies" cq-overlays-only cq-marker cq-hovershow>
	<template>
		<cq-item>
			<cq-label></cq-label>
			<span class="ciq-edit"></span>
			<div class="ciq-icon ciq-close"></div>
		</cq-item>
	</template>
</cq-study-legend>

Here is an example of how to create a study legend inside a drop down menu. We use the cq-no-close attribute so that drop down is not closed when the user removes a study from the list. 

<cq-menu class="ciq-menu ciq-studies collapse">
	<span>Studies</span>
	<cq-menu-dropdown cq-no-scroll>
		<cq-study-legend cq-no-close>
			<cq-section-dynamic>
				<cq-heading>Current Studies</cq-heading>
				<cq-study-legend-content>
					<template cq-study-legend>
						<cq-item>
							<cq-label class="click-to-edit"></cq-label>
							<div class="ciq-icon ciq-close"></div>
						</cq-item>
					</template>
				</cq-study-legend-content>
				<cq-placeholder>
					<div stxtap="Layout.clearStudies()" class="ciq-btn sm">
						Clear All
					</div>
				</cq-placeholder>
			</cq-section-dynamic>
		</cq-study-legend>
		<cq-scroll>
			<cq-studies>
				<cq-studies-content>
					<template>
						<cq-item>
							<cq-label></cq-label>
						</cq-item>
					</template>
				</cq-studies-content>
			</cq-studies>
		</cq-scroll>
	</cq-menu-dropdown>
</cq-menu>
