Interactive Control Buttons
Control Buttons let dashboard viewers filter data by clicking styled buttons, without relying on the standard filter panel. When a button is clicked, it cross-filters other visualizations on the page.
They're built inside a Dynamic Content block, where you write HTML/CSS to control the appearance and a small template tag to wire up the filtering logic.
How to set it up
Step 1: Add a Dynamic Content block and configure its data
- Add a dynamic markdown visualization to your dashboard.
- In the configure panel, add the field you want to filter by to Rows.
This queries all distinct values from your data, each one will become a button.
Step 2: Loop through the rows
Then, in the Editor tab, use {% map(rows) %} to loop through those rows:
{% map(rows) %}
<!-- one button per row -->
{% end %}
Step 3: Wrap each button with <h-drill>
Inside that loop, wrap each item with <h-drill>. This is what makes each button clickable and triggers cross-filtering on other charts. Your template should now look like this:
{% map(rows) %}
<h-drill row="0" value="{{ `Your Field`.raw }}">
<div class="your-button">{{ `Your Field`.formatted }}</div>
</h-drill>
{% end %}
row="0"tells<h-drill>which column group to filter on. For single-field filters (the most common case), this is always0.value="{{ `Your Field`.raw }}"is the raw value passed as the filter{{ `Your Field`.formatted }}is the display text shown on the button- When selected, the
.h-drill-selectedclass is added to the button element
Step 4: Connect to other dashboard components
Once your buttons are in place, other charts on the dashboard will cross-filter automatically as long as they use the same field as the button block. If a visualization isn't responding, make sure its dataset includes that same field.
Examples
Both examples below are drop-in starting points. Swap in your own field names and adjust the CSS to match your brand.
Category buttons (country filter)
Filters the dashboard by country. Requires two fields: Country (the filter value) and Country Icon (a flag emoji for display).
<style>
.country-selector {
display: flex;
gap: 1rem;
padding: 1rem;
flex-wrap: wrap;
}
.country-card {
position: relative;
display: flex;
flex-direction: column;
align-items: center;
gap: 0.5rem;
padding: 1.25rem 1.5rem;
background: #FFFFFF;
border: 2px solid #E5E7EB;
border-radius: 12px;
cursor: pointer;
transition: all 0.15s ease;
min-width: 120px;
text-align: center;
}
.country-card:hover {
border-color: #3B82F6;
background: #F8FAFC;
transform: translateY(-2px);
box-shadow: 0 4px 12px rgba(59, 130, 246, 0.15);
}
.country-card:active {
border-color: #1B7CE4;
background: #EFF6FF;
transform: translateY(0);
}
.h-drill-selected.country-card {
border-color: #1B7CE4;

.h-drill-selected.country-card > .country-label {

line-height: 1;
}
.country-label {
font-size: 0.9375rem;
font-weight: 600;
color: #111827;
}
</style>
<div class="country-selector">
{% map(rows) %}
<h-drill row="0" value="{{ `Country`.raw }}">
<div class="country-card">
<span class="country-icon">{{ `Country Icon`.formatted }}</span>
<span class="country-label">{{ `Country`.formatted }}</span>
</div>
</h-drill>
{% end %}
</div>

Quarter selector buttons (date filter)
Filters the dashboard by quarter. Add your date field to Rows and set the time-grain to Quarter. The block queries all distinct quarters from your data, so the buttons always reflect what's in the dataset.
<style>
.quarter-selector {
display: flex;
flex-direction: row;
flex-wrap: wrap;
gap: 0.5rem;
padding: 0.75rem 1rem;
align-items: center;
background: #F9FAFB;
border-radius: 8px;
}
.qs-label {
font-size: 0.75rem;
font-weight: 700;
color: #9CA3AF;
text-transform: uppercase;
letter-spacing: 0.06em;
margin-right: 0.25rem;
}
.quarter-btn {
display: inline-flex;
align-items: center;
justify-content: center;
padding: 0.375rem 1rem;
background: #FFFFFF;
border: 2px solid #E5E7EB;
border-radius: 6px;
cursor: pointer;
font-size: 0.875rem;
font-weight: 600;
color: #374151;
transition: all 0.15s ease;
min-width: 80px;
user-select: none;
}
.quarter-btn:hover {
border-color: #6366F1;
color: #6366F1;
background: #F5F3FF;
}
.h-drill-selected.quarter-btn {
border-color: #6366F1;
background: #6366F1;
color: #FFFFFF;
}
</style>
<div class="quarter-selector">
<span class="qs-label">Filter by quarter →</span>
{% map(rows) %}
<h-drill row="0" value="{{ `Quarter`.raw }}">
<div class="quarter-btn">{{ `Quarter`.formatted }}</div>
</h-drill>
{% end %}
</div>
Required data field
| Field | Type | Description |
|---|---|---|
Quarter | Date dimension | Add to Rows with time-grain set to Quarter |
Customization tips
Once the buttons are working, you can adjust their appearance to match your dashboard's design without touching the filtering logic.
- Colors: Change the border and background colors to match your brand
- Hover/selected states: Adjust
:hoverand.h-drill-selected.your-button-class(both classes must be on the same element) - Richer buttons: Add metrics, descriptions, or icons by extending the card HTML
