## Examples

### File Operations Split Button

```python
import streamlit as st
from streamlit_split_button import split_button

st.title("Document Editor")

# File operations with primary save action
file_action = split_button(
    label="Save",
    options=["Save As...", "Save Copy", "Save Template"],
    icon=":material/save:",
    key="file_operations"
)

if file_action:
    if file_action == "Save":
        st.success("✅ Document saved successfully!")
    elif file_action == "Save As...":
        filename = st.text_input("Enter filename:")
        if filename:
            st.success(f"✅ Document saved as {filename}")
    elif file_action == "Save Copy":
        st.success("✅ Copy created successfully!")
    elif file_action == "Save Template":
        st.success("✅ Template saved successfully!")
```

### Email Actions Split Button

```python
import streamlit as st
from streamlit_split_button import split_button

st.title("Email Composer")

# Email actions with primary send
email_action = split_button(
    label="Send Email",
    options=["Send Later", "Save Draft", "Send Copy to Me"],
    icon=":material/send:",
    key="email_actions"
)

if email_action:
    if email_action == "Send Email":
        st.balloons()
        st.success("📧 Email sent immediately!")
    elif email_action == "Send Later":
        schedule_time = st.time_input("Schedule for:")
        st.info(f"📅 Email scheduled for {schedule_time}")
    elif email_action == "Save Draft":
        st.info("💾 Email saved as draft")
    elif email_action == "Send Copy to Me":
        st.info("📧 Email sent with copy to you")
```

### Multiple Split Buttons

```python
import streamlit as st
from streamlit_split_button import split_button

st.title("Multi-Action Interface")

col1, col2 = st.columns(2)

with col1:
    st.subheader("User Actions")
    user_action = split_button(
        label="Create User",
        options=["Import Users", "Invite User", "Bulk Create"],
        icon=":material/person_add:",
        key="user_actions"
    )
    
    if user_action:
        st.write(f"Selected: {user_action}")

with col2:
    st.subheader("Report Actions")
    report_action = split_button(
        label="Generate Report",
        options=["Schedule Report", "Custom Report", "Quick Summary"],
        icon=":material/analytics:",
        key="report_actions"
    )
    
    if report_action:
        st.write(f"Selected: {report_action}")
```

## Design Principles

The split button follows Material Design 3 guidelines:

- **Primary Action**: The main button shows the most common or important action
- **Visual Hierarchy**: Primary button is visually prominent, dropdown is subtle but accessible
- **Consistent Spacing**: Proper padding and margins for touch-friendly interaction
- **Theme Integration**: Colors automatically adapt to your Streamlit theme
- **Hover States**: Subtle feedback when hovering over interactive elements

## Styling Details

- **Border Radius**: Rounded corners following Material Design patterns
- **Color Adaptation**: Primary color from Streamlit theme with calculated hover states
- **Typography**: Inherits Streamlit's font family and sizing
- **Shadows**: Subtle focus shadows for accessibility
- **Responsive**: Works well across different screen sizes

## Best Practices

1. **Logical Grouping**: Put related actions together in the dropdown
2. **Primary Action**: Choose the most common action as the main button
3. **Clear Labels**: Use descriptive, action-oriented labels
4. **Icon Usage**: Use icons that clearly represent the action
5. **Limit Options**: Keep dropdown options to 3-7 items for best UX
