Modal Popup

Display modal dialogs to show important information, help content, or interactive forms. This pattern uses the modal_content slot to render content in a modal overlay.

Overview​

This example demonstrates how to:

  • Create a floating trigger button
  • Open and close modals programmatically
  • Display dynamic content based on state
  • Style modal content with custom components

Help Modal​

A help modal with a floating button trigger. Perfect for displaying contact information, FAQs, or support details.

Modal

src/components/HelpModal.tsx
import { Box, Button, Text, Fragment } from "@tiendanube/nube-sdk-jsx";
import type { NubeSDK, NubeSDKState, UISlot } from "@tiendanube/nube-sdk-types";
import { styled } from "@tiendanube/nube-sdk-ui";

interface ContactInfo {
  label: string;
  value: string;
}

interface HelpModalConfig {
  title?: string;
  description?: string | ((state: NubeSDKState) => string);
  contacts: ContactInfo[];
  footerText?: string;
  closeButtonText?: string;
  triggerButtonText?: string;
  slot?: UISlot;
}

// Styled components for the modal content
const ModalContainer = styled(Box)`
  padding: 24px;
  display: flex;
  flex-direction: column;
  gap: 16px;
  background: #ffffff;
  border-radius: 12px;

// Styled button for the corner widget
const HelpButton = styled(Button)`

  margin-bottom: 16px;
`;

// Helper function to close the modal
function closeModal(nube: NubeSDK) {
  nube.clearSlot("modal_content");
}

// Helper function to open the modal
function openHelpModal(nube: NubeSDK, config: HelpModalConfig) {
  const {
    title = "Need Help?",
    description,
    contacts,
    footerText,
    closeButtonText = "Got it, thanks!",
  } = config;

  nube.render("modal_content", (state) => {
    const descriptionText =
      typeof description === "function" ? description(state) : description;

    return (
      <ModalContainer>
        <ModalTitle>{title}</ModalTitle>
        {descriptionText ? (
          <ModalDescription>{descriptionText}</ModalDescription>
        ) : (
          <Fragment />
        )}
        <Fragment>
          {contacts.map((contact, index) => (
            <ContactItem key={index}>
              <ContactLabel>{contact.label}:</ContactLabel>
              <ContactValue>{contact.value}</ContactValue>
            </ContactItem>
          ))}
        </Fragment>
        {footerText ? (
          <ModalDescription>{footerText}</ModalDescription>
        ) : (
          <Fragment />
        )}
        <Button variant="primary" onClick={() => closeModal(nube)}>
          {closeButtonText}
        </Button>
      </ModalContainer>
    );
  });
}

// Main function to set up the help modal with trigger button
export function setupHelpModal(nube: NubeSDK, config: HelpModalConfig) {
  const { triggerButtonText = "?", slot = "corner_bottom_right" } = config;

  nube.render(
    slot,
    <HelpButton variant="primary" onClick={() => openHelpModal(nube, config)}>
      {triggerButtonText}
    </HelpButton>
  );
}

// Export utilities for advanced usage
export { openHelpModal, closeModal };
export type { HelpModalConfig, ContactInfo };

Usage​

src/main.tsx
import type { NubeSDK } from "@tiendanube/nube-sdk-types";
import { setupHelpModal } from "./components/HelpModal";

export function App(nube: NubeSDK) {
  // Set up the help modal with contact information
  setupHelpModal(nube, {
    title: "Need Help?",
    description: (state) =>
      `Hi ${
        state.customer?.contact?.name || "there"
      }! If you have any questions about your order, feel free to contact us:`,
    contacts: [
      { label: "Instagram", value: "@mystore_official" },
      { label: "WhatsApp", value: "+54 11 2345-6789" },
    ],
    footerText:
      "We're here to help you with any doubts about products, shipping, or payment methods.",
    closeButtonText: "Got it, thanks!",
    slot: "corner_bottom_right",
  });
}

Configuration Options​

PropertyTypeDefaultDescription
titlestring"Need Help?"Modal title
descriptionstring \| ((state) => string)-Static text or function that receives state
contactsContactInfo[]-Array of contact items to display
footerTextstring-Optional footer text
closeButtonTextstring"Got it, thanks!"Close button label
triggerButtonTextstring"?"Floating button text
slotUISlot"corner_bottom_right"Slot for the trigger button

Dynamic Description​

The description property can be a function that receives the current state, allowing you to personalize the message:

description: (state) => {
  const name = state.customer?.contact?.name;
  const itemCount = state.cart?.items?.length ?? 0;

  if (name) {
    return `Hi ${name}! You have ${itemCount} items in your cart. Need help?`;
  }
  return "Have questions? We're here to help!";
};

Best Practices​

  1. Keep modals focused: Display only essential information to avoid overwhelming users
  2. Provide clear actions: Always include a visible close button
  3. Use appropriate triggers: Place trigger buttons where users can easily find them
  4. Consider mobile: Ensure modal content is readable on smaller screens
  5. Personalize when possible: Use state data to create personalized messages
