Design a drop-down navigation menu with the following fields: Home, Courses, Contact Information, and Address. In the Courses field, there should be a vertical navigation bar with six fields: B. Tech, M. Tech, B. Sc, M. Sc, BCA, and MCA.

\begin{tabular}{|l|l|l|l|}
\hline
Home & Courses [tex]$\downarrow$[/tex] & Contact Information & Address \\
\hline
& B. Tech & & \\
& M. Tech & & \\
& B. Sc & & \\
& M. Sc & & \\
& BCA & & \\
& MCA & & \\
\hline
\end{tabular}

Answer :

To create a drop-down navigation menu with the specified fields, we will follow a systematic approach. Let's break it down step by step.

### Step 1: Understand the Requirements
We need a horizontal navigation bar with four main fields:
- Home
- Courses (with a drop-down menu)
- Contact Information
- Address

### Step 2: Address the Drop-Down Menu for Courses
Within the "Courses" field, there will be a vertical drop-down menu that includes the following six fields:
- B Tech
- M Tech
- BSC
- MSC
- BCA
- MCA

### Step 3: Create the Structure
We will represent the initial layout in a tabular form as follows:

[tex]\[ \begin{tabular}{|l|l|l|l|} \hline Home & Courses $\downarrow$ & Contact Info. & Address \\ \hline \end{tabular} \][/tex]

This initial row includes the main navigation fields.

### Step 4: Add the Drop-Down Fields
We need to ensure that the drop-down menu appears vertically under the "Courses" field. Here's the detailed structure:

[tex]\[ \begin{tabular}{|l|l|l|l|} \hline Home & Courses $\downarrow$ & Contact Info. & Address \\ \hline & B Tech & & \\ & M Tech & & \\ & BSC & & \\ & MSC & & \\ & BCA & & \\ & MCA & & \\ \hline \end{tabular} \][/tex]

### Step 5: Visualize the Final Structure
Combining all elements, the final structure of our drop-down navigation menu in a tabular format looks like this:

[tex]\[ \begin{tabular}{|l|l|l|l|} \hline Home & Courses $\downarrow$ & Contact Info. & Address \\ \hline & B Tech & & \\ & M Tech & & \\ & BSC & & \\ & MSC & & \\ & BCA & & \\ & MCA & & \\ \hline \end{tabular} \][/tex]

### Conclusion
We have designed a drop-down navigation menu with four main fields: Home, Courses (with a downward arrow indicating a drop-down menu), Contact Information, and Address. The "Courses" field opens up to a vertical navigation bar containing B Tech, M Tech, BSC, MSC, BCA, and MCA, all properly aligned.

This structure ensures all requirements are met and facilitates a user-friendly navigation experience.
